1.14 REMOTE SETPOINT INPUT
A controller with REMOTE SETPOINT input option provides for remote linear analog current or voltage control of the
primary setpoint. Although the standard setpoint input is calibrated for 0 to 5 VDC, other voltages through 10 VDC or
currents through 100 mADC may be supplied on special order. The remote input may be from an isolated stable
current or voltage supply or, where the setpoint can be manually adjusted to the required value, it may use an internal
controller supply with a remote potentiometer for a simplified source. All controllers supplied with remote setpoint input
option have a part number whose second digit is a "1.
Controllers with remote setpoint input option can not have an ALARM/TIMER 2 as
these terminals are used for the remote setpoint input.
The rear barrier terminal connections are changed as shown below. All other connections are
as described in Section 1.
1.15 DIGITAL COMMUNICATIONS WIRING
Controllers with a digital communications option are
provided with a special Type D (DB25) connector
between the rear terminals. Wiring to this connector
is discussed in detail in Section 5.
1.16 INITIAL POWER UP
After all connections have been made to the rear terminal connections and the correct wiring verified, power may be
applied. The display should illuminate as soon as power is applied. If the multicolor vacuum fluorescent display does
not illuminate immediately, disconnect the power and recheck the wiring. Allow at least 5 minutes for warm up before
