Parameter Description
[74] Logic Rule 4 See parameter group 13-4*. If Logic Rule 4
is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[75] Logic Rule 5 See parameter group 13-4*. If Logic Rule 5
is evaluated as TRUE, the output will go
high. Otherwise, it will be low.
[80] SL Digital See 13-52 SL Controller Action. The input
Output A will go high whenever the Smart Logic
Action [38] Set digital out. A high is
executed. The input will go low whenever
the Smart Logic Action [32] Set digital out.
A low is executed.
[81] SL Digital See 13-52 SL Controller Action. The input
Output B will go high whenever the Smart Logic
Action [39] Set digital out. B high is
executed. The input will go low whenever
the Smart Logic Action [33] Set digital out.
B low is executed.
[82] SL Digital See 13-52 SL Controller Action. The input
Output C will go high whenever the Smart Logic
Action [40] Set digital out. C high is
executed. The input will go low whenever
the Smart Logic Action [34] Set dig. out. C
low is executed.
[83] SL Digital See 13-52 SL Controller Action. The input
Output D will go high whenever the Smart Logic
Action [41] Set digital out. D high is
executed. The input will go low whenever
the Smart Logic Action [35] Set digital out.
D low is executed.
[84] SL Digital See 13-52 SL Controller Action. The input
Output E will go high whenever the Smart Logic
Action [42] Set digital out. E high is
executed. The input will go low whenever
the Smart Logic Action [36] Set digital out.
E low is executed.
[85] SL Digital See 13-52 SL Controller Action. The input
Output F will go high whenever the Smart Logic
Action [43] Set digital out. F high is
executed. The input will go low whenever
the Smart Logic Action [37] Set digital out.
F low is executed.
[160] No alarm The output is high when no alarm is
present.
[161] Running The output is high when the frequency
reverse converter is running counter clockwise
(the logical product of the status bits
'running' AND 'reverse').
[165] Local reference The output is high when 3-13 Reference
active Site = [2] Local or when 3-13 Reference Site
= [0] Linked to Hand/Auto at the same
time as the LCP is in Hand on mode.
[166] Remote The output is high when 3-13 Reference
reference Site = [1] Remote or [0] Linked to Hand/
active Auto while the LCP is in [Auto On] mode.

The output is high when there is an active
command Start command (i.e. via digital input bus
active connection or [Hand On] or [Auto On],
and no Stop or Start command is active.
The output is high when the frequency
mode converter is in Hand on mode (as
indicated by the LED light above [Hand
On].
The output is high when the frequency
mode 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 Maintenance Events programmed in
23-10 Maintenance Item, has passed the
time for the specified action in
23-11 Maintenance Action.
A No-Flow situation or Minimum Speed
situation has been detected if enabled in
22-21 Low Power Detection and/or
22-22 Low Speed Detection.
A Dry Pump condition has been detected.
This function must be enabled in
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, see 22-50 End of Curve
Function.
The frequency converter/system has
turned into sleep mode. See parameter
group 22-4* Sleep Mode.
A Broken Belt condition has been
detected. This function must be enabled
in 22-60 Broken Belt Function.
The bypass valve control (Digital / Relay
Control 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
4-11 Motor Speed Low Limit [RPM]). 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. 1-71 Start
Delay can be used in order to delay the
motor start. The Bypass valve control
principle:
