After pushing the START button, STOP relays will be activated. K2/START and
K12/HORN relays are activated only when the start button is pushed.
Relays K13 and K14 on PWRSII 6-2-13 system will be activated to the corresponding
state of the Hoist Selector.
Push any of the transmitter’s motion buttons and its corresponding relay should be
activated. The safety relay K1/SEC will also be activated.
Check to make sure all other motions work in this way.
Turn OFF the transmitter using the STOP button, and make sure the relays are deactivated
and the DATA, ID and SIGNAL LEDs light corresponding to the SCANNING mode.
Reconnect the power supply to the motors, move to the usual work position and check to
see if all the motions and the STOP button are functioning correctly.
3.4 Spurious Disturbance
The receiver has designed to become blocked if there is intense spurious disturbance
arising from galvanic, inductive, or capacitive coupling, thus preventing unwanted
movement.
As a precautionary measure, it is recommended that spurious-preventing devices
(diodes, capacitors, RC circuits) be fitted at the source of the disturbance. These devices
should be connected directly to the contactor coil terminals, etc. and can be obtained
from the usual contactor suppliers.
If the equipment is installed on a crane with a friction power supply, where electric arcs
are produced as a result of defective contact, an RC circuit should be fitted between each
phase and earth.
