38 Receiving unit
Warnings for installation
5.4.3 Positioning the antenna
The antenna is inside the receiving unit. Hence, install the receiving units so
that shields, structures or materials do not obstruct the radio link; in particular:
- the receiving unit shall not be placed inside closed metal containers
- the receiving unit must be placed at least 50 cm far from metal objects in its
surroundings.
If this warning is disregarded, the radio remote control working range may be re-
duced.
5.4.4 Wiring
The receiving unit's AC power supply must be as follows:
- be protected against short circuit
- have a switch that allows power supply disconnection during installation,
wiring and/or maintenance operations.
Pay special attention to the currents flowing in the SAFETY and STOP outputs:
they shall not exceed the maximum permitted values.
To obtain the UMFS protection, connect the contact of the SAFETY relay in se-
ries with the movement commands.
Group the wiring away from the electronic module, in order to avoid interferenc-
es and hazards related to electrical safety.
The STOP circuit in the receiving unit has two contacts connected in series
through the bridge between terminal 34 and 35 (producer standard wiring). If
the machine needs a STOP circuit with two separate contacts (four wires), this
bridge can be removed. In this case, the installer is responsible for wiring in a
way that assures the required safety level.
5.4.5 At end of installation
Make sure that during installation the safety mechanisms on the radio remote
control and/or in the machine have not been made ineffective by possible pro-
cedures carried out.
Correctly close the receiving unit so that the protection degree from dust and
water is not jeopardised: check that the gasket is intact, correctly put the hous-
ing parts one over the other so that they overlap, and screw in the screws.
