REMOTE CURRENT LIMIT SETPOINT with 0-10VDC,
2-10 VDC, 0-20mA, 4-20mA or Pulse Width Modula-
tion Signal.
The Remote Current Limit setpoint can be reset over
the range of 100% to 30% Full Load Amps (FLA) by
supplying (by others) a 0-10VDC, 2-10VDC, 0-20mA,
4-20mA or 1 to 11 second Pulse Width Modulated
(PWM) signal to the Graphic Control Center. The
Graphic Control Center must be configured appropri-
ately to accept the desired signal type as follows:
• The appropriate Remote Mode must be selected:
Analog Remote Mode must be selected when us-
ing a voltage or current signal input. Digital Re-
mote Mode must be selected when using a PWM
input.
• If Analog Remote Mode is selected, the Remote
Analog Input Range setpoint must be set to "0-
10VDC" or "2-10VDC" as detailed below, regard-
less of whether the signal is a voltage or current
input signal type.
• Micro Board Program Jumper P23 must be posi-
tioned appropriately per the input signal type as de-
tailed below. It is recommended that a qualified
Service Technician position this jumper.
Important! The signal type used for
Remote Current Limit Setpoint reset
and the signal type used for Remote
Leaving Chilled Liquid Temperature
setpoint reset must be the same. For
example, if a 0-10VDC signal is be-
ing used for Remote Leaving Chilled
Liquid Temperature Reset , then a 0-
10VDC signal must be used for Re-
mote Current Limit Reset.

0-10VDC - As shown in Fig. 15, connect input to Mi-
cro Board J22-1 (signal) and J22-5 (Gnd). The setpoint
varies linearly from 100% to 30% FLA as the input
varies from 0-10VDC. This input will only be accepted
when Analog Remote Mode is selected, the "Remote
Analog Input Range" setpoint is set for 0-10 Volts,
and Micro Board Program Jumper JP23 has been re-
moved. Calculate the setpoint for various inputs as fol-
lows:
SETPOINT (%) = 100 – (VDC X 7)
For example, if the input is 5VDC, the setpoint would
be set to 65% as follows:
SETPOINT (%) = 100 – (5 X 7) = 100 – 35 = 65%
2-10VDC - As shown in Fig. 15, connect input to Mi-
cro Board J22-1 (signal) and J22-5 (Gnd). The setpoint
varies linearly from 100% to 30% FLA as the input
varies from 2 to 10VDC. This input will only be ac-
cepted when "Analog" Remote Mode is selected, the
"Remote Analog Input Range" setpoint is set for
"2-10 Volts" and Micro Board Program Jumper JP23
has been removed. Calculate the setpoint for various
inputs as follows:
SETPOINT (%) = 100 – [(VDC – 2) X 8.75]
For example, if the input is 5VDC, the setpoint would
be set to 74% as follows:
SETPOINT (%) = 100 – [(5-2) X 8.75]
= 100 – [3 X 8.75]
= 100 – 26.25 = 74%
