-55H option
Isolated Signal Input
NOTE: This option cannot be used on the 123D-C series control.
This option card allows for the use of either a grounded or non-
grounded remote DC signal such as 0 to 5 through 0 to 250Vdc,
4-20mA current, or a remote speed pot. The DC input signal type
can be selected for voltage (Vin) or current (4-20mA) via the JP2
jumper clip. There is a Hi/Lo range jumper selection that should
be set to the (Lo) setting when using a 4-20mA signal or voltage
ranges of 0-5 through 0-25Vdc. When using voltage ranges of 0-25
through 0-250 this jumper must be set to (Hi). The GAIN trimpot is
used to set full linear output in reference to the input signal range.
The output of this remote signal isolation board is a linear signal
that is proportional to the remote input signal being supplied.
(FOR SHUNT WOUND MOTOR, SEE PAGE 4 OF MANUAL FOR
FIELD CONNECTIONS).
CAUTION: DO NOT use TRIMPOT ADJUSTMENT CHART. Set pots
using directions in following SET-UP PROCEDURES.
1. With NO power to control, connect a DC Voltmeter to control outputs as follows: Meter COMMON to the -ARM terminal,
Meter POSITIVE to the +ARM terminal. Select correct meter range (0-90V or 0-180V).
2. Preset GAIN pot on the remote signal board fully CCW.
3. Place the JP2 jumper clip in the proper position based on the input signal being used.
4. Place the P4 jumper clip in the Lo position for 4-20mA signals or voltage signals less than 25Vdc. Place the P4 jumper clip
in the Hi position for voltage signals greater than 25Vdc. (NOTE: Never exceed 250Vdc)
5. Make sure all connections are properly made per the hookup connection diagram and then apply AC power to the
controller.
6. Set the remote input signal to its lowest setting. Adjust the MIN trimpot to deadband (the point just before an increase
causes an output).
7. Apply the maximum remote input signal. Motor should start to run. Adjust the GAIN pot CW until no further increase in
control output voltage occurs and then decrease the gain pot slowly until output voltage to the motor drops approximately
5Vdc.
8. Set the MAX trimpot on the control to the correct motor voltage.
9. Some interaction between trimpots may occur. Recheck the Min trimpot setting and repeat steps 6 through 8 as needed.
-56H option
Isolated Signal Input with Auto / Manual Switch
NOTE: This option cannot be used on the 123D-C series control.
The -56H option is identical
to the -55H option with the
added ability to have remote
Auto/Manual switching.
See -55H for more further
detail.
