-55G option
Isolated Voltage Input
NOTE: This option cannot be used on the 123D-C series control.
This option permits either a grounded or non-grounded re-
mote DC voltage speed command. This DC input can range
from 0-5VDC through 0-25VDC or 0-25VDC through 0-250VDC
(which can be selected via the range jumper clip and adjusted
with the GAIN trimpot). The output of this option board supplies
a linear pulse width modulated signal to the control that is
proprotional to the input signal supplied to the option board.
The option replaces the 5K speedpot. Input impedance is 1.2M
ohms on high scale, and 150K ohms on low scale.
NOTE: Range jumper connector is used to select input
voltage range. When installed from P4-1 to P4-2, the range
is 0-25VDC through 0-250VDC; when installed from P4-2 to
P4-3, range is 0-5VDC through 0-25VDC.
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 (meter must not be grounded) 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 trimpot on option board fully CCW, place range jumper clip in proper position.
3. Preset control as follows: MIN, MAX & IR fully CCW, and Current Limit fully CW.
4. Apply AC power of correct voltage to control and option board.
5. With 0 volts into option board, adjust MIN trimpot of control to eliminate deadband. To do this, increase MIN fully CW, then adjust
CCW until meter reads 0 volts.
6. Apply maximum input voltage to option board input. Motor will start to rotate.
7. Adjust GAIN until no further change in control output voltage occurs, back off approximately 1 turn, then set control MAX. setting
to 90 VDC (180VDC for 240V units).
8. Current Limit is set as shown on "TRIMPOT ADJUSTMENT CHART" on page 5.
9. For Closed Looped systems the IR should remain fully CCW. For Open Looped systems, set IR as needed
-56G option
Isolated Voltage Input with Auto / Manual Switch
NOTE: This option cannot be used on the 123D-C series control.
This option permits either a
grounded or non-grounded
remote DC voltage speed
command. This DC input can
range from 0-5VDC through
0-25VDC or 0-25VDC through
0-250VDC (which can be se-
lected via the range jumper
clip and adjusted with the GAIN
trimpot). The output of this
option board supplies a lin-
ear pulse width modulated
signal to the control that is
proprotional to the input sig-
nal supplied to the option
board. The option replaces
the 5K speedpot. Input im-
pedance is 1.2M ohms on high
scale, and 150K ohms on low
scale.
