3.6 RECEIVER/EQUIPMENT
INTERFACE CONSIDERATIONS
All output relay contacts are rated for 10 Amps 277VAC/30VDC, 1 HP 240VAC for maximum life and
surge protection, and protected with MOVs. Connection to equipment or contactors with higher voltage or
current requirements will require intermediate relays.
Relay outputs K1-K11 are normally open, single pole single throw (SPST) relays. Relay output K12 is a
normally open, dual pole single throw (DPST) relay. Relay outputs K13-K14 are Form C “flip-flop” relays
(flip-flop relays contain both normally open and normally closed outputs). Since a relay closure is only
active while the transmitter unit key is pressed and held, devices such as lights or lifting magnets must
use a mechanical auxiliary latching relay.
3.7 RECEIVER
UNIT
ENCLOSURE MOUNTING
When mounting the receiver, make sure to allow room for the door to swing open. Mount the receiver
unit cabinet securely to the mounting surface. Actual cabinet mounting dimensions are shown in Section
3.9.
3.8 RECEIVER
INSTALLATION
1. Be sure to mount the receiver antenna in direct line-of-sight of the operator and free from all
obstructions.
2. Do not mount the receiver near high levels of electrical noise, such as unshielded variable frequency
drives, as they may cause minor interference. When mounting the in
tele
Smart2 near unshielded
variable frequency drives Magnetek typically recommends that the in
tele
Smart2 and all antenna cable
routing be mounted a minimum of 24 inches from all unshielded variable frequency drives and cables.
3. Allow adequate room for mounting the receiver. Be sure to allow a minimum of 12.7cm (5 in) between
the connector and nearest surface to allow for cable harness connections.
4. For best reception, and to help protect connectors from moisture and water damage, mount the
receiver such that the external antenna connector is pointing straight up and the connections come
out the bottom of the unit. Placement of the antenna needs to be in a location such that there is line
of sight between the antenna and the transmitter. Refer to Section 3.3 for additional antenna
mounting considerations.
5. If obstructions cannot be cleared, or if the unit must be mounted inside of a metal enclosure, the
remote antenna should be used.
6. Do not enclose the antenna in steel. If the receiver is mounted within an enclosure, an external
antenna MUST be used. For the best reception, keep all metal objects away from the antenna.
Consult the factory for more information regarding your application.
7. The supply power to the in
tele
Smart2 system must have a master disconnect and should be fused.
8. It should not be necessary to set the Access Code or channel, as they are preset. If special field
programming is needed, power the unit up on the bench and program the unit for any special
configurations or other parameters (see Section 7 for details). The unit can be re-programmed after it
is installed if necessary.
9. Position the receiver; make sure to locate it as far as possible from exposed trolley wire and sources
of electromagnetic or radiated noise. Enclosure mounting dimensions and mounting can be found in
Figure 1.
10. Mount the receiver. Refer to Section 3.9 for further information regarding mounting.
11. Wire the unit using the electrical drawings shown in Section
Error! Reference source not found.

12. Wire the power input for the input power type as described in Section 4.2.
