How to Programme the Low Ha...
[120] Lead Pump Starts/Stops the Lead Pump (controlled by
Start the frequency converter). A start requires
that also a System Start signal has been
applied e.g. to one of the digital inputs set
for [8] Start!
[121] Lead Pump Forces alternation of the lead pump in a
Alternation Cascade Controller. Lead Pump Alternation,
25-50 Lead Pump Alternation must be set to
either [2] At Command or [3] At Staging or At
Command. Alternation Event,
25-51 Alternation Event can be set to any of
the four options.
[130 Pump1 The function will depend on the setting in
- Interlock - 25-06 Number of Pumps. If set to [0] No,
138] Pump9 then Pump1 refers to the pump controlled
Interlock by relay RELAY1 etc. If set to [1] Yes, Pump1
refers to the pump controlled by the
frequency converter only (without any of
the build in relays involved) and Pump2 to
the pump controlled by the relay RELAY1.
Variable speed pump (lead) cannot be
interlocked in the basic Cascade Controller.
