Second Contact Option

All keypads are factory set to switch the V1 (+24V) supply to the VALVE1B+ pins in the same way as the VALVE1A+ pins. By changing the 'Second Contact Configuration Jumpers' it possible to change this action to a volt free contact closure across VALVE1B+ and VALVE1B- pins. The same is true for all eight channels.

WARNING!
Care must be taken when changing this configuration as incorrect positioning  of the jumpers will permanently damage the unit.
Under no circumstances should this operation be performed with the power switched on.
