EWTS 330/S Time Actuator to Manage Work Cycles Technical Data Sheet EWTS 330/S

M1 version: time actuator with digital inputs and alarm relays • M2 version: outputs manual commands or from dgital inputs EWTS 330/S includes an internal clock to control timings. An internal back-up device permits time count for about one hour in case of power failure. A range of alphanumeric parameters allows configuring EWTS 330/S according to requirements. EWTS 330/S and EWTS SLAVE are supplied in the 70x85 mm format (4 modules) for Din rail (Omega 3) or wall mount. •

OUTPUT CONTROL GENERAL DESCRIPTION EWTS 330/S is a microprocessor-based digital instrument designed to operate as time actuator to manage time cycles. This instrument controls three relays that are included in the EWTS SLAVE Din module, that also powers the instrument to which it is connected through a special MULTIPLE WIRE cable. This cable is provided with disconnectable polarised telephone connectors on both ends and conveys all the input and control signals to the module relays, and the power supply voltage to the EWTS 330/S master. EWTS 330/S includes a 4 digit led display and four configuration keys for the manual operation of users, a 12 Vc /20 mA voltage output to drive a fourth relay for the management of operation alarms (e.g. recovery after a power failure), and 3 inputs for the users remote control. It is also provided with an RS-485 port (doubled to ease cabling) for the connection to the TELEVIS system. The Instrument is available in 2 different versions suitable for different applications:

The control of the outputs are 4: Automatic, Manual, Output Programming, Remote. -Automatic: the instrument manages a range of 40 events that can be configured through the keyboard or the TELEVIS SYSTEM. An event is identified by settings in the “Exx” type user menus, which are accessible from parameters programming. The structure of each event menu is described in Tab.2. The relay status will be updated in correspondence with the operation time of each set event. Manual operation of outputs has a higher priority on event operation. This is in force until the following event. Weekly events have higher priority on daily events according to the order in Tab.2. In this way an event programmed for all weekdays can be cancelled by a different weekly event (for instance on Mondays). Not vice-versa. Parameter “CUSt”, in detail, allows to set a custom sequence of days of the week for which it will be executed the events related to the Custom period. Range of

this parameter is 0 (no days) to 127 (all days). Intermediate values show all the list of possible days. To calculate the value proceeed as follows: Calculate the decimal number corresponding to the binary number LMMGVSD where you set to 1 the days of the week taht you consider, and at 0 the others (See Example in Tab. 3) On every event, each output can be set to five different modes: unchanged, active, inactive, pulse, free-running and toggle. Through the “dxc” parameters it is possible to set a constant delay time for each output that on each event allows to “freeze” the output status and delay its status change. The operation times for each output in the bistable and pulse cycles can be set through parameters “tx1” and “tx2”. Parameter “PrEn” can be used to disable event management while keeping the program stored. In this case outputs can only be operated manually or through digital input. -Manual: by operating on keys Out 1, Out 2 and Out 3 the three connected users can be manually enabled or disabled. -Output programming: the logical status of the outputs can be modified through the keyboard. The setting modes allow to generate an asynchronous event from the keyboard, which is similar to events automatically actuated by the chronometer (see Automatic Mode). -Remote: digital inputs can be configured to remote activate the connected users through special contacts.

REAL TIME PROGRAMMING EWTS 330/S is provided with an internal clock. To change the set time, hold keys “St-by” and “Out 2” pressed for more than 7 seconds. The current time with the blinking minute digits will be displayed. The “UP” and “DOWN” keys can be used to set the required value, key “Out 1” switches to the following field setting (time – day – minutes in sequence). The field being modified blinks. To exit time programming and confirm the set value press key “St-by”. EWTS 330/S is provided with an internal back-up device that allows continuing time count in case of power failure. Autonomy is about 1 hour; then the real time is cancelled from the instrument memory and shall be re-

programmed (in fact the count is set to “h00”-“00'” at start-up). OUTPUT PROGRAMMING To change the logical status of outputs, hold keys “St-by” and “Out 3” pressed for more than 7 seconds. This enters output status programming mode, indicated by the blinking “P” on the first display. The other three displays show the logical status of outputs which is initially set to “nnn”. This programming mode allows actuating users according to a logical sequence in the same way as an event of the automatic event programming would do. Use keys “UP” and “DOWN” to change the status of output indicated by the blinking display and key “Out 1” to confirm setting and activate the following output setting. At the end of selection confirm the last change through the “Out 1” key and press “Stby” to operate. EMERGENCY CYCLE The device provides the management of an emergency cycle that can be enabled through parameters “bAE”,“diAx” and “PoAE”. During the emergency cycle the three users are enabled according to settings made through parameters “SO1E”, “SO2E” and “SO3E”. The alarm signal Emergency user is operated during the emergency cycle according to the mode set through parameters “SOE”, “tE1”,“tE2” and “dEc”. The length of the emergency cycle is determined by parameter “ECd”. At the end of the emergency cycle due to time-out the Emergency user is turned off. Parameter “EcP” can be used to assign the emergency cycle a higher priority on programming. If the emergency cycle is active, letter “E” is displayed on the first display . Black-Out In case of power failure for less than the backup-capacity (about 60 minutes), if the “PoAE” parameter is set to value “n”, when recovering from the black-out the users shall be initially turned off and the display will show Short Black Out error until the first time event or key pressure. By setting parameter PoAE to “y” the emergency cycle can be activated in case of Short Black Out. The alarm is reset by pressing any key or on the first time event.

Long Black Out. In case of power failure for more than the backup capacity, the time count will be locked to “00” of day “1” (Monday) and the outputs disabled. Initially users shall be turned off and the display indicates the Long Black Out error. Parameter bAE can be used to enable the emergency cycle even in case of Long Black Out. Setting the time resets alarm. Digital Input Emergency cycle is activated through a digital input if parameter “diAx” is enabled. If parameter “did” (detect digital input) is set to LEL (LEveL) the digital input related to emergency handled on the level as follows: • presence of digital input (see also polarity) = Active emergency status (if it was not terminated by timeout); • absence of digital input (see also polarity) = Disabled emergency status. If parameter “did” (detect digital input) is set to EdE (EdgE) digital inputs are handled on the front as follows: • positive front (see also polarity) = emergency status toggle. STAND-BY FUNCTION The stand-by function allows to “freeze” the status of outputs by inhibiting the actions of programming and emergency cycle. It can be performed through a digital input or the instrument keyboard (manual). For both modes two parameters (“dSE” and “hSE”) are available to enable the function. Both the digital input, whose polarity is set through parameter “diPx”, and the keyboard activation sequence have the same effect on all outputs. The maximum function time can be set through parameter “Sbt”. When set to 0, there is no limit to duration. The standby function also affects the emergency cycle. In case of manual stand by the first display shows letter “S”. In case of digital input stand by the first display shows a blinking “S”. Digital Input If parameter “did” (detect digital input) is set to LEL (LEveL) the digital input related to stand-by is handled on the level as follows:

EWTS 330/S 3/8

presence of digital input (see also polarity) = Active stand-by status (if it was not terminated by time-out); • absence of digital input (see also polarity) = Disabled stand-by status. If parameter “did” (detect digital input) is set to EdE (EdgE) digital inputs are handled on the front as follows: • positive front (see also polarity) = stand-by status toggle. •

OPERATING USERS FROM DIGITAL INPUTS Users can also be controlled by the related digital inputs: keys di1(OUT1), di2(OUT2) and di3(OUT3). The polarity of digital inputs is controlled by “dPx” parameters –an active state involves the activation of the related user. Digital Input on level If parameter “did” (detect digital input) is set to LEL (LEveL) the digital inputs are handled on level as follows: • presence of digital input (see also polarity) = forced activation of the connected user. The display shows letter d to indicate the output is forced to high value by digital input. The digital input action has no effect on output programming. When the digital input is disabled the output takes the programming value, as if no d.i. event had occurred. Digital Input on front If parameter “did” (detect digital input) is set to EdE (EdgE) the digital inputs are handled on front as follows: • positive front (see also polarity) = toggle of the connected user. This operation also affects programming as the output status is permanently changed until the following event. DIAGNOSTIC The ELbo blinking label indicates the instrument has lost the time memory due to a prolonged electrical black out. Set the time to cancel the signal. The ESbo blinking label indicates the instrument was turned on and no event is active. In this case the time memory has been kept. Press any key to cancel the signal. The fourth display is used to indicate the instrument status during the user status display. Acceptable values are: • “ ”: normal operation; • “S”: stand-by from digital input (blinking);

• • •

“S”: stand-by from keyboard; “P”: output programming; “E”: Active emergency.

PARAMETERS Parameters are visible in two different tables (Parameter description table) which describes the parameter function and while the second table (Parameter features table) provides for a list of the specific features of each parameter. PARAMETERS – EVENTS PROGRAMMING Holding keys “St-by” and “Out 1” pressed for more than 7 seconds enters programming mode. The first user parameter label is displayed. Press the “UP” or “DOWN” key (“Out 2”and “Out 3”) to skip to the other user parameters’ label. To display the value of a user parameter indicated by the label press key “Out 1”. To change it press key “UP” or “DOWN”; to exit parameter setting press key “Out 1” again. The newly set values are automatically stored when programming mode is exited, either when no key is pressed for 10 seconds or by pressing the key during parameters label display. The instrument allows setting a password to access parameters programming mode. To set (or change) the password access parameter “PAS” and introduce a value between 1 and 120 (setting value 0 disables the password). The password will be enabled when exiting parameters programming mode. In case the password is enabled label “PASS” is displayed as access to the parameters programming mode is requested. Press key “Out 1” to access password setting, it can be modified through keys “UP” and “DOWN”. If the password is correct, pressing the “Out 1” key will permit to access programming mode, otherwise it will automatically exit. Parameter “Menu” is used to enter event setting mode. When key “Out 1” is pressed while displaying label “Menu”, the label of the first event, “E00”, will be displayed (if the label is preceded by the minus sign “-” it means the current event is not used). The “UP” and “DOWN” keys can be used to browse the list of events (from 0 to 39). Pressing the "St-by" key in correspondence with the required event can access the event programming sub menu.

The event programming submenus are composed by a series of 6 labels through which all the event variables can be set, in the same modes as in the parameters programming menu. ELECTRICAL CONNECTIONS The instrument is provided with a telephone connector for the connection to the EWTS SLAVE Din module, and with a screw terminal block for the connection of electrical cables with a 2.5 mm2 section (one wire only per terminal according to VDE regulations). EWTS SLAVE is provided with a telephone connector for the connection to the master module, two screw terminal blocks for the connection of electrical cables with a 2.5 mm2 section (one wire only per terminal for power connections). Check the power supply voltage of EWTS SLAVE complies with the instrument requirements. Relay outputs are free from voltage. Do not exceed the maximum allowed current; in case of heavier loads use a suitable power contactor. The connection cables for digital inputs can be lengthened by a common bipolar cable (please remember that too long cables decrease the instrument performances related to EMC electromagnetic compatibility). Outputs for the connection to the TELEVIS system require compliance to indicated polarity. Cables for digital inputs, the connection cable between the two modules and the TELEVIS serial port shall be kept far from relay cables both for EMC and safety reasons. The European coordinated regulations require that relay contact wires (and generally speaking all parts subject to dangerous voltage) shall be separate from very low safety voltage sections (probes and Televis serial) through insulation and distances to ensure at least a double or reinforced insulation. EMC requirements for correct operation suggest / impose to take more care in such separation by using separated insulating raceways and special cable fixing fittings.
