SETTING FOR MODEL BB - EB (SETUP)
Set 01 Inputs from external contacts
Setup:

0 = Inputs from external contacts Disabled
1 = Inputs from external contacts Enabled
Set 02 Pulse time
Pulse time from 0.05 to 5.00 sec.
Set 03 Interval time
Interval time between ev. from 1 to 999 sec.
Set 04 Number of cleaning solenoid valve selection
Set 05 Number of additional cycles after fan stop
Set 06 Manual TEST of every single ev. 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.
Set 07 Operation selection AUTOMATIC / MANUAL
Setup

0 = Manual
1 = Automatic (Cleaning by dP values)
Set 08 Output voltage setup for ev. (see HV). Necessary for right operating of B8a
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.
Set 09 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, when the plant stops or air pipes are not connected, if the dP reading is not 0.00 kPa it is possible to adjust it by key A and C.
Set 10 1st dP threshold, STOP cleaning since low dP
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.
Set 11 2nd dP threshold, START cleaning since high dP
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.
Set 12 Maximum dP alarm threshold.
Set 13 Additional cycles mode selection
In set up it is possible to select the mode to manage the fan and the post-cleaning cycles:

SET F13 = 0 (not avaliable with C11a option)
If you connect a voltage-free 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 the keyboard from 0 to 99.
Post-cleaning cycles can be also activated when dP = 0.
If the D1a contact is open, the display will show both '-0-' and the dP reading alternated, to indicate that the cycle is not working because the fan is off.
The decimal points on the display will flash on and off during the cycles after the fan stops.
NOTE D1a: Connect D1a by means of a jump if it is not used with active inputs (see F01).

SET F13 = 1
If the dP control is activated, you can add a pre-set number of cleaning cycles after the fan stop. Their number can be set from the keyboard from 0 to 99. The Timer compare the dP readout with a 0.20 kPa fixed threshold.
When dP readout goes down under 0.20 kPa the additional cleaning cycles start if the dP readout should reach the cycle STOP threshold value during the normal operation.
The decimal points on the display will flash on and off during the additional cycles.
With dP < 0.20 kPa the display shows '-0-' and the dP reading alternatively.
