|Options on request. Contact us for other options|
|D5a||Consent from external compressed air pressure switch||If the operation mode is automatic and contact D5a is open, the cleaning cycle stops, relay K2 indicates the alarm situation. Close D5a to restart the washing cycle from the point where it had stopped. If contact D5a is open, the display shows alarm code E6.
NOTE: Link D5a clamps if it is not used with inputs from external contact active.
• A: Contact D5a Open
• B: Contact D5a Close
• C: Alarm Relay Contact Open
• D: Alarm Relay Contact Close
|Inp3||Third digital input||On request it is possible to have a third digital input.
This entrance can be:
• Additional contact cycles (D1a3)
• Automatic operation / Manual by contact (C9a)
• Activation of additional cleaning cycle (C2d)
• Other functions on request
|K3||Third relay contact in output||On request it is possible to have a third relay contact at the output.
This relay can control:
• Tribo probe alarm (D11a)
• ON / OFF cleaning cycle (A3a)
• Minimum dP alarm (A1c)
• Other functions on request
|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
|B10b||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 C to select the desired output to be activated. Press key A to activate the output.
The output is holded active for all the time that key A 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.|
|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.
|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.
|D1a||Additional cycles after fan stop||By connecting an auxiliary volt-free contact of the fan circuit with the sequencer, it is possible to add a well-defined number of cleaning cycles after the stop of the fan. Their number is selectable from 0 to 99 from the keyboard. The activation of post-cleaning cycles starts even if C6 contact is open. If contact D1a is open, the display shows '-0-' to indicate cycle stop for fan Off. During the cycles after the fan stop, the decimal points blink on the display. NOTE D1a: Link D1a clamps if it is not used with active inputs (see F01).|
|D6||ON/OFF Cleaning cycle from external contact.||If contact D6 is open, the cleaning cycle is not enabled and the display shows 'OFF'.
With sequencer with digital dP control the display shows 'OFF' and the dP reading alternatively.
By closing D6, the cleaning cycle can start from the first electrovalve.
NOTE D6: Link D6 clamps if it is not used with inputs from external contact active. (see 5.1 : SETUP F01).
|G1||Maximum load power 25W per output||Maximum load power 25W per output|
|HV||Input / Output voltage selection.||Use the jumpers on the board to select the supply voltage and the output voltage on the electrovalves.
