[54] Auto start A signal applied will put the frequency converter into Auto mode as if the LCP button
Auto On
has
been pressed. See also
Hand Start
[53]
[55] DigiPot Increase Uses the input as an INCREASE signal to the Digital Potentiometer function described in parameter
group 3-9*
[56] DigiPot Decrease Uses the input as a DECREASE signal to the Digital Potentiometer function described in parameter
group 3-9*
[57] DigiPot Clear Uses the input to CLEAR the Digital Potentiometer reference described in parameter group 3-9*
[60] Counter A (up) (Terminal 29 or 33 only) Input for increment counting in the SLC counter.
[61] Counter A (down) (Terminal 29 or 33 only) Input for decrement counting in the SLC counter.
[62] Reset Counter A Input for reset of counter A.
[63] Counter B (up) (Terminal 29 and 33 only) Input for increment counting in the SLC counter.
[64] Counter B (down) (Terminal 29 and 33 only) Input for decrement counting in the SLC counter.
[65] Reset Counter B Input for reset of counter B.
[66] 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 Maintenance 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 The function will depend on the setting in par. 25-06, Number of Pumps. 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 inter-
locked in the basic Cascade Controller.
See below table:
Setting in Par. 5-1* Setting in Par. 25-06
[0] No [1] Yes
[130] Pump1 Interlock Controlled by RELAY1
(only if not lead pump)
Frequency Converter control-
led
(cannot be interlocked)
[131] Pump2 Interlock Controlled by RELAY2 Controlled by RELAY1
[132] Pump3 Interlock Controlled by RELAY3 Controlled by RELAY2
[133] Pump4 Interlock Controlled by RELAY4 Controlled by RELAY3
[134] Pump5 Interlock Controlled by RELAY5 Controlled by RELAY4
[135] Pump6 Interlock Controlled by RELAY6 Controlled by RELAY5
[136] Pump7 Interlock Controlled by RELAY7 Controlled by RELAY6
[137] Pump8 Interlock Controlled by RELAY8 Controlled by RELAY7
[138] Pump9 Interlock Controlled by RELAY9 Controlled by RELAY8
