SL Control Action
See par. 13-52 . The input will go high whenever the Smart Logic Action [42]
dig. out. E high is executed. The input will go low whenever the Smart Logic Action [36]
out. E low is executed.
See par. 13-52 SL Control Action . The input will go high whenever the Smart Logic Action [43]
dig. out. F high is executed. The input will go low whenever the Smart Logic Action [37]
out. F low is executed.
The output is high when no alarm is present.
The output is high when the frequency converter is running counter clockwise (the logical product
of the status bits 'running' AND 'reverse').
The output is high when par. 3-13
Linked to hand auto
[0] at the same time as the LCP is in Hand on mode.
The output is high when par. 3-13
the LCP is in [Auto on] mode.
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.
The output is high when the frequency converter is in Hand on mode (as indicated by the LED light
above [Hand on].
The output is high when the frequency converter is in Hand on mode (as indicated by the LED light
above [Auto on].
The clock function has been reset to default (2000-01-01) because of a power failure.
One or more of the Preventive Maintenance Events programmed in par. 23-10, Preventive Mainte-
nance Item, has passed the time for the specified action in par. 23-11, Maintenance Action.
A No-Flow situation or Minimum Speed situation has been detected if enabled in
Detection . par. 22-21 and/or No-Flow Detection
A Dry Pump condition has been detected. This function must be enabled in par. 22-26, Dry Pump
Function.
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
The frequency converter/system has turned into sleep mode. See
A Broken Belt condition has been detected. This function must be enabled in par. 22-60, Broken
Belt Detection.
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
it
, 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.
lay , par. 1-71 can be used in order to delay the motor start. The Bypass valve control principle:
