Receiver Installation

Make sure the machine on which the receiver is to be attached is

disabled while during installation.

Turn off the main line disconnect switch. Check the power supply

voltage. MAKE SURE THE POWER SUPPLY IS OFF.

For a crane, park the crane and position the end stops at a suitable

distance so that other cranes on the same runway do not hit it. If end

stops are not available, use appropriate signs instead.

Keep the work area free from unnecessary clutter.

Wear protective clothing.



Note: Before installing the receiver, make sure that the outputs diagram supplied with the

system is available.



Note: Installations subject to vibration should install the optional Shock Absorber Kit part #

1166074 available at Cervis. The kit has four absorbers that you place between the receiver

and the mounting surface as per the kit directions.



Note: Always mount the receiver and antenna away from

any intense radio or electric disturbance sources.



Note: When using contactors with the system, it is advisable

to use arc suppressors, such as MOV’s, by installing them

across the coil of the contactors as shown in Figure 3.



Note: If necessary, it is possible to improve signal reception

by using the extension cables and external antenna kit. See

Figure 5.

3. Find a suitable location for the receiver with clear

access to the transmitter radio signal. Figure 4 below

shows the footprint of the receiver and illustrates the

distance between the mounting holes.
