6-1. Wiring Diagrams.
Your TELE
PILOT
system comes pre-
programmed
t
he following pages in this section
have individual wiring diagrams for different
crane configurations. Find the appropriate wiring
diagram and if necessary set the Configuration
Switch (SW3 in the transmitter) to match the
SW3 Transmitter Switch Settings shown in the
appropriate diagram. The location of the SW3
for Membrane and Pendant transmitters is shown
in Section 8-1. Servicing. Terminal designators
are marked on the wiring diagram corresponding
to designators found on the Receiver Board. For
terminal locations see Figure 8-1. Receiver
Layout. After selecting the appropriate motors
for each function remember to use the
appropriate label on your tele
Pilot
transmitter
for describing the appropriate command.
For the Pendant and Membrane transmitters the
proper connections to use for the bridge and for
the trolley are best determined by that pair of
directional designators (North/South or
East/West) best describes the crane’s movement.
Does the bridge travel East/West or
North/South? The trolley would use the other
directional pair as the bridge. Care should be
taken after a directional pair is selected to make
sure the specific motor directional inputs match
the desired direction of the bridge or trolley, i.e.,
if North/South is picked for the bridge make sure
the South traveling bridge motor directional is
wired to the South terminal of the unit.
Typically in the following wiring diagrams, the
bridge is shown as Motor 3 and Trolley as Motor
2. Since the labeling cannot be easily moved on
the Membrane Transmitter keypad, the two
directional pairs Motor 2 and 3 can be easily
exchanged by turning the dip switch SW3
position 1 in the Membrane Transmitter to
“ON”. See Section 7-6.8. Repositioning of
Membrane Transmitter Motion Switch Functions
for more details.
6-2. Installation.
Follow Section 4. Installation Procedure for
instructions on how to install the receiver.
6-3. Alarms And Horns.
Make sure that the installation includes the
proper alarms, horns, indicator lights and their
associated controls as required by local and
governmental regulations.
6-4. Single-Speed Pendant Transmitter
Wiring.
For the Single-Speed Pendant Transmitter the
only wiring configuration is the diagram in
Section 6. Wiring. Table 1, TR12 Single-Speed
Standard Configuration Hoist, Trolley and
Bridge.
6-5. 2-Speed Pendant Transmitter Wiring.
For the 2-Speed TR12 Pendant Transmitter the
functional labeling is different than the 2-Speed
Membrane. E/W and N/S are exchanged. By
setting dip switch SW3 position 1 in the “ON”
position the pushbuttons of the Pendant
Transmitter match the directional notations on
the 2-speed wiring diagrams in Section 6.
Wiring. Failure to turn switch SW3 position 1 to
“ON” will cause EAST/WEST and
NORTH/SOUTH to be exchanged respectively.
All other functions will remain the same.
6-6. Relay Sequencing.
When the second speed position is activated the
appropriate directional relay is still engaged.
6-7. Alarm After E-STOP.
This is only for wiring configurations where the
Aux 3 (relay K12, output J5-6) is being used for
the Alarm function, placing a jumper on JU1 on
the Receiver Board will allow the alarm to
function after an E-STOP command. See Figure
8-1. Receiver Layout for jumper location.
6-8. Connecting Outputs To Drives.
MOV’s (transient protectors) are on all the
output relays to protect the relays from power
surges. MOV’s allow a small leakage current
that can affect some high impedance circuits.
When connecting output relays to drives, it may
be required to remove the MOV to prevent the
leakage current through the MOV from holding
in the drive. See Figure 8-1. Receiver Layout for
the location of the MOV's. The MOV’s are next
to the relays they protect. The MOV’s can be cut
