[161] Running reverse The output is high when the adjustable frequency drive is running coun-
ter-clockwise (the logical product of the status bits ‘running’ AND ‘re-
verse’).
[165] Local reference active The output is high when par.3-13
Reference Site = [2] Local or when par.
3-13
Reference Site = [0]
Linked to hand auto
at the same time as the
keypad is in [Hand on] mode.
[166] Remote reference active
The output is high when par.3-13
Reference Site [1] or
Linked to hand/
auto
[0] while the keypad is in [Auto on] mode.
[167] Start command active The output is high when there is an active start command (i.e., via digital
input bus connection or [Hand on] or [Auto on], and no stop command
is active.
[168] Drive in hand mode The output is high when the adjustable frequency drive is in Hand on
mode (as indicated by the LED light above [Hand on].
[169] Drive in auto mode The output is high when the adjustable frequency drive is in Hand on
mode (as indicated by the LED light above [Auto on].
[180] Clock Fault The clock function has been reset to default (2000-01-01) because of a
power failure.
[181] Preventive Maintenance One or more of the preventive maintenance events programmed in par.
23-10
Maintenance Item has passed the time for the specified action in
par.23-11
Maintenance Action.
[190] No-Flow A No-Flow situation or Minimum Speed situation has been detected if
enabled in par.22-22
Low Speed Detection.
[191] Dry Pump A dry pump condition has been detected.
[192] End of Curve A pump running with max. speed for a period of time without reaching
the set pressure has been detected. To enable this function, see par.
22-50
End of Curve Function.
[193] Sleep Mode The adjustable frequency drive/system has set to sleep mode. See par.
22-4*.
[194] Broken Belt A broken belt condition has been detected. This function must be ena-
bled in par.22-60
Broken Belt Function.
[195] Bypass Valve Control The bypass valve control (digital/relay output in the adjustable frequency
drive) is used for compressor systems to unload the compressor during
start-up by using a bypass valve. After the start command is given, the
bypass valve will be open until the adjustable frequency drive reaches
par.4-11
Motor Speed Low Limit [RPM]). After the limit has been reached
the bypass valve will be closed, allowing the compressor to operate nor-
mally. This procedure will not be activated again before a new start is
initiated and the adjustable frequency drive speed is zero during the re-
ceiving of start signal. par.1-71
Start Delay can be used in order to delay
the motor start. The bypass valve control principle:
