How To Install GuardSwitch Series 151 Non-Contact Interlock/Position Switch

Description

Edwards Signaling 151 Series interlock/position switches are specially designed for use in washdown applications.

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.

• Surges from coils, motors, contactors, solenoids and tungsten filaments. 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.

• Line capacitance and load capacitance. An in-line resistor can be added in series immediately before the load to limit the inrush current. The resistor can only be added in series with the last wire just before the load. The voltage drop and the power rating of the resistor must also be calculated as follows:

Voltage drop = I • R Watts = I2 • R
( I = maximum continuous current of the load)

To verify Sentrol switch operation with an ohmmeter:

Set range at 20 mega ohms (switches with triac output, set ohm range at 20 kilo ohms). For a normally open Interlogix switch, the meter will read a high impedance with the actuator away. It will read very high to infinity range (triac switches will read high kilo ohm to infinity range) with the actuator within sense range. You will see the opposite reading for a normally closed GE Security switch.

Mounting Configurations

How To Install GuardSwitch Series 151 Non-Contact Interlock/Position Switch

Three configurations are appropriate for interlock applications. The parallel actuation can result in on/off/on signal if the actuator passes by the switch rather than coming to rest in proximity to it. This is NOT a recommended configuration for interlock applications.
 
Installation

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

1. Using the following guidelines, determine a suitable mounting location

• The switch and actuator must be within the listed sense range. See Ordering/ Electrical Specifications.

• The actuator must be aligned with the switch - labels facing the same direction. See Figure 1.

Important: When mounting the 151/153 in proximity to ferrous material (steel), the sense range can be reduced 50% minimum depending on the shape and type of material.

• When mounting on ferrous material (steel), a 1/4" nonferrous (plastic or aluminum) spacer may be used under the actuator and switch to restore most of the lost gap.

• When mounting on a hinged gate or door, mount the switch and actuator at least 6" away from the hinges to achieve the maximum movement.

• The switch and actuator must move in one of the approved directions. See figure 2.

• The actuator can be mounted at a 90° rotation to the switch.

• Do not mount for parallel actuation. An on-off-on signal may result when the actuator passes by the switch.

2. Mount the switch on the stationary frame of the machine and connect the electrical wiring. When mounting the switch on an ungrounded machine, connect the ground lead to one of the mounting screws.

3. Mount the actuator on the movable guard, door, or gate.
