Wiring Method
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring, or
making wiring connections, to prevent electrical shock
or equipment damage.
NOTE: When attaching two or more wires to the same termi-
nal, other than 14 AWG (2.0 sq mm), be sure to twist
them together. Deviation from this rule can result in
improper electrical contact (see Fig. 13).
Each terminal can accommodate the following gauges of wire:
— Single wire: from 22 AWG to 14 AWG solid or stranded
— Multiple wires: up to two 18 AWG stranded, with 1/4 watt
wire-wound resistor
Prepare wiring for the terminal blocks, as follows:
1. Strip 1/2 in. (13 mm) insulation from the conductor.
2. Cut a single wire to 3/16 in. (5 mm). Insert the wire in
the required terminal location and tighten the screw.
3. If two or more wires are being inserted into one terminal
location, twist the wires together a minimum of three
turns before inserting them (see Fig. 13).
4. Cut the twisted end of the wires to 3/16 in. (5 mm)
before inserting them into the terminal and tightening
the screw.
5. Pull on each wire in all terminals to check for good
mechanical connection.

Controller Replacement (PVL0000AS,
PVL4022AS, and PVL6436AS)
For PVL0000AS, PVL4022AS, and PVL6436AS controllers,
which are hard-wired to an actuator, perform the following
actions to replace the complete assembly (controller and
actuator):
1. Remove all power from the controller.
2. Remove the two air flow pickup connections from the
pressure sensor.
3. Remove the terminal blocks.
4. Remove the old controller and actuator assembly from
its mounting.
• Loosen the two bolts on the actuator clamp to
release the actuator from the shaft.
• Remove the controller’s mounting screws.
• Gently pull the controller and actuator assembly
straight out, until the assembly is clear of the
actuator shaft.
