PNEUMATIC KILL SWITCH

CHECK AND ADJUSTMENT

A kill switch has been mounted in the bottom bar

assembly. The purpose of this switch is to prevent the

door from being operated if the breakaway bottom bar

becomes separated from either side column.

Reversing Edge Switch Sensitivity Adjustment

1. The reversing edge switch is a normally open con-

tact. The PVC hose is on the lower air input post. To

adjust the switch, first remove the wires and resistor

from the contact terminals and attach an ohmmeter

across the two terminals. (See Figure 42.)

2. Turn the adjustment screw, located on the face of the

switch, clockwise or counterclockwise until continuity is

achieved. Then turn the screw two full turns

counterclockwise. The ohmmeter should no longer show

continuity. Turning the screw counterclockwise decreases

sensitivity. Turning the screw clock- wise increases

sensitivity. (See Figure 42.)

Reversing

Take precautions to prevent the door from

being opened or closed while performing

the following procedure.

1. Raise or lower the door to approximately head or

chest height and stop the door.

NOTE: It should not be possible to restart the door

until the door has been reassembled and

the control system reset.

2. Push the breakaway bottom bar out of the side

column. Door should not operate until control box is

reset. (See Figure 43 and Figure 44.)

If the kill switch did not operate properly:

Adjust

the kill switch and then recheck it. (See “Kill Switch

Air Bleed Adjustment” on page 17.)

If the kill switch operated properly:

Reinstall the

bottom bar into the side column. (See “RESET-

TING BOTTOM BAR ASSEMBLY” on page 18.)

3. Reattach resistor and wires and then replace the

access cover on the bottom bar.

NOTE: If the reversing edge is set too sensitive,

the door may reverse direction during the

closing cycle, without the reversing edge

coming in contact with an object. If this

occurs, readjust the reversing edge

switch.
