Sleep Mode
Forces frequency converter into Sleep Mode (see par. 22-4*, Sleep Mode). Reacts on the rising edge of signal
applied!
[78]
Reset Preventive Main-
tenance Word
Resets all data in par. 16-96, Preventive Maintenance Word, to 0.
The below setting options are all related to the Cascade Controller. Wiring diagrams and settings for parameter, see group 25-** for more details.
[120]
Lead Pump Start
Starts/Stops the Lead Pump (controlled by 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
Start
[8]!
[121]
Lead Pump Alternation Forces alternation of the lead pump in a Cascade Controller.
Lead Pump Alternation
, par. 25-50, must be set to
either
At Command
[2] or
At Staging or At Command
[3].
Alternation Event
, par. 25-51, can be set to any of
the four options.
[130 - 138]
Pump1 Interlock -
Pump9 Interlock
For the above 9 setting options, par. 25-10, Pump Interlock, must be set to
On
[1]. The function will also depend
on the setting in par. 25-05, Fixed Lead Pump. If set to
No
[0], then Pump1 refers to the pump controlled by
relay RELAY1 etc. If set to
Yes
[1], 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.
See below table:
Setting in Par. 5-1*
