Patented Non-Contact

Safety Interlock Switch

Installation

Use non-removable screws, bolts, or nuts to mount the switch and actuator. Do not

over-torque mounting hardware.

1. Do not wire the switch until it is mounted and tested. (See Testing/Wiring)

2. Select a mounting location where the switch and actuator can be installed with

their labels reading in the same direction. (See Figure 1.)

3. Mount the switch on the stationary frame of the machine and the actuator on the

moveable guard, door or gate.

4. For best protection against operator defeat, mount with non-removeable screws,

bolts, or nuts. (See accessories)

5. The switch and actuator must be mounted so that the actuator moves in one of

the approved directions (See Mounting Configuration, Figure 2).

6. Parallel actuation is NOT recommended and may cause switch failure. An on/off/

on signal may result when the magnet passes by the switch rather than coming

to rest in proximity to it. (See Mounting Configuration, Figure 2)

7. When mounting on a hinged gate or door, mount the switch and actuator at least

6" away from the hinges so a more parallel movement is achieved.

8. The actuator can be mounted at a 90° rotation.

9. Keep the switch and actuator within the listed sense range (See Ordering/

Electrical Specifications).

10. Mounting on a ferrous (steel) material will reduce the sense range a minimum of

50%. A 1/4" nonferrous (plastic or aluminum) spacer installed under the actuator

and switch will restore most of the lost gap.

11. When mounting a metal switch to an ungrounded machine, connect the ground

lead to one of the switch mounting screws.

Warning! To avoid switch failure determine the actual load of the switch circuit and

take steps to protect the switch from voltage spikes, current inrush and line/load

capacitance using the following recommendations. If the installation instructions are

not followed carefully, the switch may not work properly or fulfill its failsafe function,

or it may fail prematurely.

Surges

from coils, motors, contactors, solenoids and tungsten filaments must

be considered.

2. Transient protection, such as back-to-back zener diodes (Transorb) or an RC

network, is recommended for such loads to ensure that maximum ratings of the

switch are not exceeded.

3. Line capacitance and load capacitance must be considered. An in-line resistor can

be added to limit the inrush current.

4. The resistor can only be added in series with the last red wire just before the load.

5. The voltage drop and the power rating of the resistor must be considered.

Voltage drop = I • R

Watts = I

• R

( I = maximum continuous current of the load)

Note: If the installation instructions are not followed carefully, the switch may not

work properly or fulfill its failsafe function, or it may fail prematurely.
