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.
