B10c	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 A over and over again to activate outputs sequentially. When key A 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 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.
B1c	Select Number of outputs	The BUS line can drive up to 12 remote unit RU with maximum 8 electrovalves each one, for maximum 96 electrovalves per line.
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.
D1a	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. The activation of post-cleaning cycles starts even if C6 contact is open. If contact D1a is open, the display shows '-0-' to indicate cycle stop for fan Off. During the cycles after the fan stop, the decimal points blink on the display. NOTE D1a: Link D1a clamps if it is not used with active inputs (see F01).
G1	Maximum load power 25W per output
HVA	Input voltage selection	By some jumpers on the board it is possible to change the supply voltage. (See label on the device pr board layout). The ouput voltage for the electrovalves (BUS line) is fixed 24VDC. JP1: Supply voltage selection between 115VAC or 230VAC.
