Application
The S1A GR and S2A GR auxiliary switches are used to
indicate when a desired position of a damper is reached or to
interface additional controls for a specific control sequence.
Operation
The S1A GR and S2A GR auxiliary switches are mounted
onto the direct coupled actuator. The switches are modular
units that mount directly onto TLM, TNM, TAM, and TGM type
actuators and are locked into place by guiding grooves on the
sides of the actuator.
A driver disk is attached to the actuator clamp and offers
direct transmission of the actuator position to the micro switch
cams. The switching points can be set over the full scale of
0 to 1 simply by adjusting the slotted discs.
Mounting Instructions
1. Remove position indicator from actuator.
2. Press down the manual override button and rotate the
actuator fully counter-clockwise.
3. Turn the driver disk on the switch fully counterclockwise.
4. Slide switch onto the actuator using the actuator guiding
grooves on the sides of the actuator.
5. Check for correct mating of the driver disk to the
universal clamp.
6. Adjust switch dials as necessary.
