[160] No alarm The output is high when no alarm is present.
[161] Running reverse The output is high when the frequency converter is running counter clockwise (the logical product of the status
bits ‘running’ AND ‘reverse’).
[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 LCP is in Hand on mode.
[166] Remote reference ac-
tive
The output is high when par. 3-13
Reference Site = Remote
[1] or
Linked to hand/auto
[0] while the LCP 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 or Start command is active.
[168] Drive in hand mode The output is high when the frequency converter 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 frequency converter 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 Mainte-
nance
One or more of the Preventive Maintenance Events programmed in par. 23-10, Preventive 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
Minimum Speed Detection
. par.
22-21 and/or
No-Flow Detection
, par. 22-22.
[191] Dry Pump A Dry Pump condition has been detected. This function must be enabled in par. 22-26, Dry Pump Function.
[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 please see
par. 22-50 End of Curve Function
.
[193] Sleep Mode The frequency converter/system has turned into sleep mode. See
Sleep mode
, par. 22-4*.
[194] Broken Belt A Broken Belt condition has been detected. This function must be enabled in par. 22-60, Broken Belt Detection.
[195] Bypass Valve Control The bypass valve control (Digital / Relay output in the frequency converter) 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 frequency converter reaches
Motor speed low limit
, par. 4 -11) . After the limit has
been reached the bypass valve will be closed, allowing the compressor to operate normally. This procedure will
not be activated again before a new start is initiated and the frequency converter speed is zero during the
receiving of start signal.
Start Delay
, par. 1-71 can be used in order to delay the motor start. The Bypass valve
control principle:
[196] Fire Mode The frequency converter is operating in Fire Mode. See 24-0*
Fire Mode
.
[197] Fire Mode was act. The frequency converter has been operating in Fire Mode, but is now back in normal operation.
[198] Drive Bypass To be used as signal for activating an external electromechanical bypass switching the motor direct on line. See
24-1*
Drive Bypass
