RCDs, Timers, Over/Under voltage relays, Earth Leakage Devices, Contactors and Thermal Overload Relays
may be connected to these outputs to provide 3 phase operation, additional protection and/or
funcionality.
Upgrades and Modifications
The following parts of the system can be upgraded at any time without any modification to the control
panel.
Replacement/upgrade of pump(s)
Replacement/upgrade of solenoid(s) or motorised valve(s)
Replacement of Level Probe, Switch or other input device.
Note – there is no need to reprogram or adjust the control panel settings when replacing a pump with
one of a different power output or consumption. Diagnostic functions are not dependent on current
monitoring.
Installation of 3 phase pump(s) via external contactor/relay.
When extending a probe or sensor cable a shielded and vented sensor cable must be used, otherwise the
level display reading and hence operation based on levels will be inaccurate.
DO NOT use mains flex, FP200, twin & earth, network cable, etc.
Software upgrade by either on-site reprogramming, or by CPU replacement. Reprogramming is unlikely to
ever be necessary, but is provided for to allow for custom software to be retrofitted to the control panel. It
is carried out by an approved engineer via an on-board programming port, or via replacement of the CPU.
The CPU is socketed in a 40pin DIP socket for ease of replacement.
When replacing the CPU, always use a proper DIP Extraction Tool, and follow the instruction provided with
the replacement CPU.
