|Some options on request. Contact us for other options|
|C11a||4÷20 mA output signal of dP readout||4÷20 mA output signal corresponding to the dP reading.
The signal is active, supplied at 12VDC by the device, the maximun drived load is 450 Ohm.
4mA = dP reading 0.00 kPa, 20 mA = dP reading equal to the full range requested.
If an external voltage is applied to C11a clamps the device will be damaged.
• A: Max 450 Ohm
|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
|AL1||Alarm relay contacts open||The relay contacts signaling the presence of alarm are open if there is no supply or in presence of alarm condition. With power supply on and in the absence of an alarm, the contact is closed.
Relay contacts: 42 VAC - 5 A Max / 42VDC - 3A Max
• A: Contact open in alarm
|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.|
|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.
|C1||Digital differential pressure control (STOP at cycle end)||In automatic running mode (C4a), the cleaning cycle is activated and deactivated according to the dP readout.
C1a Set the cleaning STOP threshold: if dP is below this threshold, the cleaning cycle stops and the display shows 'CYCLE STOP FOR LOW dP' or the letter 'P' according to the model.
The cleaning cycle stops at the end of the cycle (Set 13).
C1b Set the cleaning START threshold: if dP is above this threshold, the cleaning cycle is activated (Set 14)
|C13_10||dP full range 10.00 kPa = 100.0 mbar = 1012 mmH2O.||Maximum differential pressure value measurable by the device 10.00 kPa = 100.0 mbar = 1012 mmH2O.
With dP reading over 10 kPa the display shows 'E' instead of the numeric value of dP.
|C4||Cleaning cycle||If all the requirements for the start-up of the cleaning cycle are fulfilled when supply is powered on (e.g. fan on, external consents C6 or D5, dP readout above the start threshold), the sequencer will automatically activate the EV outputs sequencially according to the times set by keyboard.|
|C4a||Automatic operation mode||By keyboard in Setup it is possible to select the operation mode. In automatic mode, the controls of the fan, the dP, C6 and D5 are active and the activation of the cleaning cycle will depend on such functions.|
|C4b||Manual operation mode||By keyboard in Setup it is possible to select the operation mode. In manual mode, the control of the fan, the dP, C6 and D5 are not active.|
|C7c1||Minimum dP alarm. Automatic reset.||If the dP readout is below the threshold set in Set up, the minimum dP alarm is activated.
The display shows the alarm condition code E8 (see the alarm description) or the dP readout and letter L alternatively, according to the model.
The corresponding alarm relay will signal its condition.
The alarm is automatically reset when the dP readout is above the threshold again.
With set value 'OFF' or 'E' (according to the model), the function is excluded.
NOTE: the minimum dP alarm is delayed by 60 seconds by default after the activation of the first cleaning cycle.
|C7d1||Maximum dP alarm. Automatic reset.||If the dP readout is above the threshold in Set up, the maximum dP alarm is activated. The display shows the alarm condition code E7 (see the alarm description) or the dP readout and letter H alternatively, according to the model.
The corresponding alarm relay will signal its condition. The alarm is automatically reset when the dP readout is below the alarm threshold again.
The activation of this alarm is delayed by 20 seconds by default.
|C8||dP zero readout regulation||In this set up code it is possible to adjust the zero reading of differential pressure.
In this function the display shows the dP reading and, with plant stops or air pipes not connected if the dP reading is not 0.00 kPa it is possible to adjust it by key A and C.
|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.
|D1b1BC||Additional post-cleaning cycles from dP readout. Activation at STOP.||In automatic operation mode, 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. The sequencer will automatically recognise the fan state by comparing the dP readout with the threshold in set code F11: dP > set F11 = fan on, dP < set F11 = fan off.
Post-cleaning cycles are activated even if dP = 0. When the fan is off or dP < set F11, the display shows '-0-'.
On the display during additional cycles the decimal points blink.
Post-cleaning cycles are activated only if the dP readout should reach the threshold value of cycle STOP in normal operation mode.
|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
|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).
|DPa||Air connections 6x4 RILSAN pipe|
|G1||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.
