SETTING FOR MODEL SB - LSB (SETUP)
Set 01 ENABLE / DISABLE digital inputs from external contacts
Setup

0 = Disabled
1 = Enabled

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.
Set 03 Pulse time
Pulse time from 0.05 to 5.00 sec.
Set 04 Interval time
Interval time between ev. from 1 to 999 sec.
Set 05 Interval time between ev. during post-cleaning
Interval time between ev. during post-cleaning from 1 to 999 sec.
Set 06 Number of 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.
Set 07 Number of cleaning solenoid valves selection
The selection of the number of outputs to be control led 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 ones.
Minimum load 5W ÷ 12 W depending on the output voltage.
If the load is below of the minimum, the autoselection does not work correctly, set the number of outputs in set up.
Set 08 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 A to select the desired output to be activated. Press key C to activate the output.
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.
Set 09H Functioning hour counter (Thousand, Tens of thousand)
Set 09L Functioning hour counter (Units, tens, hundreds)
Set 17 Input 2 function (14-15)
Setup:

0 = C6
1 = D6

C6 : If contact C6 is open, the cleaning cycle stops at the end of the whole cleaning cycle and the display shows 'P', which means stop for low dP.
If contact C6 is closed, the cleaning cycle restarts from the beginning.
NOTE C6: put a jumper on C6 if it is not used with active inputs.

D6 : 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.
Set 18 Output voltage selection for ev. (see HVB). Necessary for right operating of B8b
Set the same output voltage you have selected by means of the jumpers to adjust the trip threshold of the short-circuit.
Otherwise, the sequencer might malfunction or be damaged.
