The following procedure recommends the

use of a continuity meter to determine when the

auxiliary switch opens or closes. If such a meter

is not available, it is possible to hear the switch

click as the contacts open and close.

1. Remove the control module cover.

2. Move the output shaft to the desired switch

position.

3. Disconnect power from the drive.

4. Connect the continuity meter across the

normally closed terminal on the terminal

board (terminals 6 and 7 for S1, and 3 and 4

for S2). Adjust the cam until the meter shows

no continuity (switch contacts open, switch

clicks). See Fig. 2, page 13.

5. Disconnect the meter and reconnect actuator

power.

6. Extend/Retract the output shaft in the

direction away from the switch position. Note

the direction of rotation of the lobe of the cam.

The correct cam lobe motion is away from

the switch lever and the switch lever should

be on the lower part of the cam. If this is not

correct, return to step 2 and reset the cam to

the proper orientation.

7. Reconnect the meter and actuator power.

8. Extend/Retract the output shaft again to the

desired switch position. If the contacts close,

the switch is properly set.

9. Replace the control module cover.

SETTING AUXILIARY SWITCHES

(S1 & S2)

All versions of Group 42 actuators referenced

in this manual are shipped with two auxiliary

switches. They may be set at any point in the

active range of actuator travel. Unless otherwise

specified at time of order, these switches are

factory set as follows:

Auxiliary switch S1 is set approximately 2%

(4.32 mA feedback) before the retract limit.

Auxiliary switch S2 is set approximately 2%

(19.68 mA feedback) before the extend limit.

The auxiliary switches are opened and closed

by cams that are driven by the actuator output

shaft. Setting the switch position involves moving

the actuator output shaft to the desired position

and adjusting the cam so that it just actuates the

switch at that point.

CAUTION

Do not attach the meter or attempt

to adjust the switch cams until the

actuator is discon nected from the

line voltage and auxiliary switches

are disconnected from external

power sources.
