UCP1 valid.
For units fitted with a configuration board, the UCP2 and/or UCP3 are not being detected.
3
RED/GREEN Flashing
2 second period
UCP1 valid.
For units fitted with a display, the unit requires site set-up.
This state does not occur if the unit is fitted with a configuration board.

Remedy
:
1
Check that UCP1 is fitted to plug fitted to CR4 pins 7 & 8 for units with Alpha-numeric
display or fitted to configuration PCB part number 1150634, which is fitted to CR4 if no
display is fitted (see section 1.5.3 of manual for more details). Ensure that good electrical
contact is made in each case.
2
Check that the jumpers J1 & J2 on the configuration PCB are correctly fitted, to select the
site water quality and site control signal (see section 1.5.3 of the manual).
3
Enter “Set-up unit”, enter the “control signal” type and “site voltage”, see Alpha-numeric
display module operating manual.
4
Once the unit has been “set-up” press ok at the prompt “Apply changes are you sure *?*”
when the unit will exit this state.
5
Check that the jumper J2 (on the configuration PCB) is correctly fitted, selecting the
correct site water type (see section 1.3.1 of the “Installation, Operation & Maintenance
Manual”).
