|C11a||4๗20 mA output signal of dP readout||4๗20 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
|LC2||Transparent membrane for keyboard IP65||Transparent PVC membrane to put on the device to protect the keypad.
The degree protection of this membrane is IP65.
|A1aoc||Minimum and maximum dP alarms on same open collector output||Minimum and maximum dP alarms act on the same open collector output. The display will specify the type of alarm.|
|AL1oc||Open collector outputs without voltage en alarm||The open collector outputs that signaling the presence of alarm do not supply voltage if there is an alarm condition.
In the absence of an alarms, 24VDC 200mA maximum is available.
Do not overtake the maximum corrent val๒ue indicated to avoid damage to the device.
|B10a||Manual activation of every single output from keyboard||From the keyboard you can manually and individually activate every single output for an operation test. Press key C over and over again to activate outputs sequentially. The output is kept active as long as key C is held down and the display shows ON. When key C is relesed, the number of the output will increase automatically to the next one. 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.|
|B1a||Selection of the Number of outputs||Every BUS line can drive up to 12 RU-xB modules of maximum 8 outputs for ev. each one.|
|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)
|B8boc||Short-circuit protection of every single output||In case of short-circuit, the corresponding output is automatically skipped. The open collector output 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.
|B9boc||Electric control of output activation||If a solenoid valve is not activated, the open collector output indicate the alarm condition and the display shows the alarm condition code E2 (See alarm description). Press key 'E' to reset alarm condition. ATTENTION: this function will be active only if the automatic selection of the load in set up is not selected. The alarm switch on after 5 consecutive fails on the same output.|
|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.
|C3||Differential pressure readout from internal transducer (max 10 kPa)|
|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.|
|C7c1oc||Minimum dP alarm. No voltage in alarm. Automatic reset.||If the dP readout is below the threshold 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 open collector output will signal its condition. The alarm is automatically reset when the dP readout is above the threshold again.
If set to '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.
|C7d1oc||Maximum dP alarm. No voltage in 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 open collector output 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.
|D1b1||Post-cleaning cycles from dP readout. Activation at STOP.||In automatic operation mode, you can 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 11: dP > set 11 = fan on, dP < set 11 = fan off. Post-cleaning cycles are activated even if dP = 0. When the fan is off or dP < set 11, the display shows 'FAN STOP'. The display shows 'POST-CLEANING ACT' during additional cycles and if there is no alarm. Post-cleaning cycles are activated only if the dP readout should reach the threshold value of cycle STOP in normal operation mode.|
|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
