Potential Electrocution Hazard. If this equipment is used outdoors or in potentially wet locations, a
Ground Fault Interrupt device must be used for connecting the equipment to its mains power source.
DANGER
Electrocution Hazard. Do not connect AC power to a 24 VDC powered model.
WARNING
Potential Electrocution Hazard. A protective earth (PE) ground connection is required for both
100-240 VAC and 24 VDC wiring applications. Failure to connect a good PE ground connection can
result in shock hazards and poor performance due to electromagnetic interferences. ALWAYS connect
a good PE ground to the controller terminal.
NOTICE
Install the device in a location and position that gives easy access to the disconnect device and its operation.
The controller can be purchased as either a 100-240 VAC powered model or a 24 VDC powered
model. Follow the appropriate wiring instructions for the purchased model.
The controller can be wired for line power by hard-wiring in conduit or wiring to a power cord.
Regardless of the wire used, the connections are made at the same terminals. A local disconnect
designed to meet local electrical code is required and must be identified for all types of installation. In
hard-wired applications, the power and safety ground service drops for the instrument must be 18 to
12 AWG.
Notes:
• The voltage barrier must be removed before making any electrical connections. After making all
connections, replace the voltage barrier before closing the controller cover.
• A sealing type strain relief and a power cord less than 3 meters (10 feet) in length with three 18gauge conductors (including a safety ground wire) can be used to maintain the NEMA
4X/IP66 environmental rating.
• Controllers can be ordered with AC power cords pre-installed. Additional power cords may also be
ordered.
• The DC power source that supplies power to the 24 VDC powered controller must maintain
voltage regulation within the specified 24 VDC-15% +20% voltage limits. The DC power source
must also provide adequate protection against surges and line transients.
Wiring procedure
Refer to the illustrated steps that follow and Table 1 or Table 2 to wire the controller for power. Insert
each wire into the appropriate terminal until the insulation is seated against the connector with no
bare wire exposed. Tug gently after insertion to make sure that there is a secure connection. Seal
any unused openings in the controller box with conduit opening sealing plugs.

English 15
The wiring compartment is not designed for voltage connections in excess of 250 VAC.
24 VDC powered controllers
WARNING
Potential electrocution hazard. AC mains powered controllers (115 V–230 V) are designed for relay
connections to AC mains circuits (i.e., voltages greater than 16 V-RMS, 22.6 V-PEAK or 35 VDC).
WARNING
Potential electrocution hazard. 24 V powered controllers are designed for relay connections to low
voltage circuits (i.e., voltages less than 16 V-RMS, 22.6 V-PEAK or 35 VDC).
The 24 VDC controller relays are designed for the connection to low voltage circuits (i.e., voltages
less than 30 V-RMS, 42.2 V-PEAK or 60 VDC). The wiring compartment is not designed for voltage
connections above these levels.
The relay connector accepts 18–12 AWG wire (as determined by load application). Wire gauge less
than 18 AWG is not recommended.
The Normally Open (NO) and Common (COM) relay contacts will be connected when an alarm or
other condition is active. The Normally Closed (NC) and Common relay contacts will be connected
when an alarm or other condition is inactive (unless the Fail Safe is set to Yes) or when power is
removed from the controller.
Most relay connections use either the NO and COM terminals or the NC and COM terminals. The
numbered installation steps show connection to the NO and COM terminals.

• Pulse Width Modulation Control Function (refer to Figure 24)
Option
Description
Set mode
Auto—the relay output works as a PID controller.
Manual—the signal is controlled by the user through manual adjustment of the % change
value. This option is shown as Manual Output after the manual set mode is selected.
Phase
Reverses the leading sign of the control deviation for the PID controller (default: Reverse). The
phase selects whether the relay will operate at the first part of a cycle (direct phase) or the
second part (reverse phase).
Set setpoint Creates a setpoint value.
Dead zone
The range above and below the setpoint. In this set range, the PID controller does not take
action to change the Pulse Width Modulation On/Off Ratio output signal until the limits of the
dead zone are reached.
Period
Sets the cycle duration of the PWM output signal (default: 5 seconds).
Min width
Sets the minimum PWM ratio (default: 1.0 second).
Max width
Sets the maximum PWM ratio (default: 4.0 seconds).
Prop band
Sets the proportional part of the PID controller. The proportional part of the controller supplies
an output signal which is linearly dependent to the control deviation. The proportional part
reacts on any changes at the input but starts to oscillate easily if the value is set high. The
proportional part cannot completely compensate for disturbances.
Integral
Sets the integral part of the PID controller (default: 000 minutes). The integration part of the
controller supplies an output signal. The output signal increases linearly if the control deviation
is constant. The integration part responds slower than the proportional part and can completely
compensate disturbances. The higher the integration part, the slower it responds. If the
integration part is set too low, it starts to oscillate.

0.001–60.000 (default: 04.000). This value cannot be set lower than Minimum Pulses value.
Prop band
Sets the proportional part of the PID controller. The proportional part of the controller
supplies an output signal which is linearly dependent to the control deviation. The
proportional part reacts on any changes at the input but starts to oscillate easily if the value
is set high. The proportional part cannot fully compensate for disturbances.
Integral
Sets the derivative part of the PID controller (default: 000 minutes). The integration part of
the controller generates an output signal. The output signal increases linearly if the control
deviation is constant. The integration part responds slower than the proportional part and
can fully compensate disturbances. The higher the integration part, the slower it responds.
