|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
|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
|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)
|B8a||Short-circuit protection of every single output||In case of short circuit, the output is automatically skipped, the relay K1, normally active, is deactivated and the terminal board contact opens.
The display alternatively shows code E1 and the number of the faulty output.
Press key B 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.
|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.
|C1d||Differential pressure digital control||If dP control is active (Set F07 = 1), the cleaning cycle starts and stops according to the dP reading.
With dP reading under the STOP threshold the cleaning cycle stops and the display shows dP reading and letter P alternatively. The cleaning cycle stop is at the end of the cycle.
With dP reading over the START threshold the cleaning cycle is able to start.
|C3||Differential pressure readout from internal transducer (max 10 kPa)|
|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.
|D1ab1||Additional cycles after fan stop with fan mode selection.||In set up it is possible to select the fan management and post-washing cycles:
SET F13 = 0 (not available with option C11a) Adds a number of wash cycles after the fan stop can be set from 0 to 99. The activation of cycles also occurs with dP = 0.
SET F13 = 1 The sequencer compares the dP reading with a fixed threshold of 0.20 kPa. The cycles are activated below 0.20 kPa
|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||Maximum load power 25W per output|
|HVC||Input voltage selection||By some jumpers on the board it is possible to change the supply voltage. (See label or board layout).
JP1: Supply voltage selection between 115VAC or 230VAC.
|PL-T||Electropilot 24VDC||1/8'' Pilot valve for pneumatic activation of the valves.
Degree protection: IP65.
Standard coil voltage: 24VDC
Pressure: 0.5÷7.5 bar
Temperature: -20°C ÷ +80°C
