[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
Output A See 13-52 SL Controller Action . The input
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
Output B See 13-52 SL Controller Action . The input
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
Output C See 13-52 SL Controller Action . The input
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
Output D See 13-52 SL Controller Action . The input
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
Output E See 13-52 SL Controller Action . The input
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
Output F See 13-52 SL Controller Action . The input
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
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 3-13 Reference
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
reference
active
The output is high when 3-13 Reference
Site
=
[1] Remote
or
[0] Linked to Hand/
Auto
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
Maintenance
One or more of the Preventive
Maintenance Events programmed in
23-10 Maintenance Item , has passed the
time for the specified action in
23-11 Maintenance Action .
[190] No-Flow 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 .
[191] Dry Pump A Dry Pump condition has been detected.
This function must be enabled in
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, see
22-50 End of Curve
Function .
[193] Sleep Mode The frequency converter/system has
turned into sleep mode. See parameter
group 22-4*
Sleep Mode .
[194] Broken Belt A Broken Belt condition has been
detected. This function must be enabled
in
22-60 Broken Belt Function .
[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
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:
