|A2a||Relay Voltage ON (K1)||If the device is supplied, relay K1 is activated and the terminal board contact is closed. In case of power failure, this contact is open.
• A: Relays
• B: Terminal board
|B10||Manual activation of every single output from keyboard||By keyboard, it is possible to activate manually and individually every single output for an operation test.
Press key A to select the desired output to be activated. Press key C to activate the output.
The output is holded active for all the time that key C is pressed. It allows to measure the output voltage by using a tester.
In case of anomalous operating, do this test with electrovalves disconnected.
|B1b||Selection Number of outputs||The selection of the number of outputs to be controlled is connected by keyboard in SET MODE.
If you set 0 or AUTO in this function, the sequencer will automatically select the connected loads by skipping the non connected outputs.
Minimum load 5W ÷ 12 W depending on the output voltage. If the load is below 5 W, autoselection does not work properly. Set the number of outputs in set up.
|B2x||Activation time from 0.05 to 5.00 sec.|
|B3c||Interval time between ev. during post-cleaning||Interval time between two activations settable by keyboard when post-cleaning cycles are active and during the forced cycles of option C2x if available.
The selection range is the same as the inteval time in standard operation mode (B3x).
|B3x||Interval time from 1 to 999 sec.||If the pulse time is lower than 1 sec. it is possible to set any interval time value in the range indicated.
If the activation time is higher than 1 sec. the minimum settable interval time is:
Minumum interval time = 5 times pulse time (B2x)
|B8b||Short-circuit protection of every single output||In case of short-circuit, the corresponding output is automatically skipped. Relay K2 will signal the alarm condition and display will show the alarm situation code E1 (See the alarm description).
Press key E to reset the alarm.
|C0||Input activation from external contacts||In Set up you can activate or deactivate the control of all the inputs of the device.
If inputs are deactivated, they are considered as always closed and no jumper is required on the terminal board.
Use a jumper for unused inputs if you activate them.
NOTE: all inputs of the device have to be connected to external contact without voltage.
|C4c||Cleaning cycle||If all the conditions necessary for the start of cleaning cycle (e.g. fan On, external consents C6 or D6 present) are present when supply voltage is switched on, automatically the device activates the outputs in sequencial way with timing set by keyboard|
|C6a||ON/OFF cleaning cycle from external pressure switch. STOP at the end of the cycle||With digital inputs enabled and with contact C6a open the cleaning cycle stops at the end of the cleaning cycle and display shows 'CYCLE STOPS FOR LOW dP'.
When C6a is closed the cleaning cycle restart. NOTE. Put a wire between the clamps of input C6a if not used with inputs enabled.
|D14a||Operation hours-counter||In Setup it is possible to visualize an hours counter.
This counter is active when the cleaning cycle in On.
In case of fan stop, consent D6 not present or with the device in Setup the counter stops.
|D1a3||Additional cycles from voltfree contact. ALWAYS enabled.||By connecting an NO auxiliary contact of the circuit intended to drive the fan with the sequencer, it is possible to add a pre-set number of cleaning cycles after the fan stop.
Their number can be set from 0 to 99 by keyboard. Post-cleaning cycles are activated even if dP = 0 or C6x open.
If contact D1a3 is open, the display shows the indication of fan stop (See operation table 6.1). The display shows 'POST-CLEANING ACT' or decimal points blink, according to the model, during additional cycles.
NOTE. Jump D1a3 clamps if it is not used with inputs enabled.
|D6a||ON/OFF cleaning cycle from external contact||If contact D6a is open, the cleaning cycle is not enabled and the display shows 'START CONTACT D6a OPEN'.
Close D6a to start cleaning cycle from the first electrovalve.
NOTE D6a: Jump D6a if it is not used with inputs from external contact active.
• A: Contact D6a Open
• B: Contact D6a Closed
|G1||Maximum load power 25W per output|
|SL||Multi language display||In Set up it is possible to select the language of all the descriptions showed by the display:
