Fig. 27 — PremierLink Control Wiring to

Q769C Adapter and Actuator

Economizer with Johnson 4 to 20 mA Actua- tor — The PremierLink Controller can be connected to an economizer that uses a Johnson 4 to 20 mA actuator.

DRIVE DIRECTION — The actuator drive direction is dependent upon the position of Switch 3 and the spring return direction. See Table 5. The actuator is factory set for Direct Acting (DA) operation with Switch 3 in the DA position. An increasing control signal drives the actuator away from the spring return position in DA mode. The actuator should be installed in the DA mode so damper will close automatically on power shut down.

If Reverse Acting (RA) operation is desired, move Switch 3 to the RA position. An increasing control signal drives the actuator toward the spring return position in RA mode.

SWITCH SELECTION — The type of input control signal is determined by the position of Switch 5. With Switch 5 in the VDC position (factory setting), the signal is DC voltage. With Switch 5 min the mA position, the input signal changes to current input. See Fig. 28 and Table 6. The switch should be set to mA for use with PremierLink controller.

NOTE: To change the factory setting, use a 1/8-in. (3-mm) flat-blade screwdriver to position the mode switch to the alter- nate setting.

WIRING (See Fig. 29-30B) — The wires for power and signal transmission from PremierLink to economizer are field- supplied. To connect the Economizer Johnson Actuator to PremierLink controller, connect the pink wire on actuator to purple wire on PremierLink J9-1. See Fig. 30A.

For the Belimo Actuator, connect the white wire on the ac- tuator to J9-1 on the PremierLink controller. See Fig. 30B.

NOTE: To retrofit PremierLink Controller to older 4 to 20 mA actuator, connect the red wire on the actuator wire harness to the purple wire on the PremierLink J9-1. Connect the yellow and white wires from the actuator wire harness to the 24-volt AC transformer on equipment. See Fig. 29.

IMPORTANT: Make sure the common side is grounded for both the PremierLink power and the actuator power. This is especially important if separate transformers are used.
