VERIFY PROPER VOLTAGE AND OPERATION

The TFT Extend-A-Gun RC has built in circuit protection to guard against a circumstance where the unit's movement is blocked before
reaching its full travel limits. Without this circuitry the motor would stall, overheat, and could be permanently damaged. This circuit works
by detecting the increase in electrical motor current that occurs when the motor stops turning at the end stops or if the travel is blocked
by an obstruction. Low voltage due to improper wire gauge, poor connections, or a weak battery may affect the operation of the Extend-
A-Gun RC motor protection.
Once installation and all connections are complete, follow these steps to verify proper voltage and operation:
1. Apply power to control box
2. Press UP button (if available) or AUX1 button from any TFT RC monitor operator station. Extend-A-Gun RC should fully extend.
3. Once Extend-A-Gun RC motor stops, attempt to turn the manual override knob counterclockwise to verify that the motor has been
disengaged from the circuit. If the motor cannot be turned by hand, this indicates that the motor has not been disengaged from
the circuit and electrical power is still applied. If this occurs, the most likely cause is the voltage supplied to the Extend-A-Gun RC
is too low.
4. Press DOWN button (if available) or AUX1 button from any TFT RC monitor operator station. Extend-A Gun RC should fully
retract**.
** If Extend-A-Gun RC is connected to TFT RC monitor, RC monitor must be in "PARK" position before the Extend-A-Gun RC
will retract. Pressing DOWN (if available) or AUX1 button will automatically command RC monitor to PARK.
The Extend-A-Gun RC can also be retracted by pressing the P (PARK) button on any TFT RC monitor. The RC monitor will perform the
PARK procedure and then the Extend-A-Gun RC will automatically go down.
If a low voltage situation to the Extend-A-Gun RC is suspected, the wiring needs to be checked for proper gauge for the installed length
of wire, and proper termination. Ensure that the power source supplying the Extend-A-Gun RC and grounding is adequate (other
electrical loads on a shared circuit with the Extend-A-Gun RC may cause a low-voltage situation).
In addition to motor damage, low voltage could cause the unit to not extend and retract properly or fully.

RETRACTED AND EXTENDED RELAY WIRING

The Extend-A-Gun RC contains a magnetic switch that is
connected to a DOWN relay inside the control box. The magnetic
switch and DOWN relay are energized when the Extend-A-Gun
RC is in the retracted position.
The control box also contains a USER relay which can be
configured for the installer's needs
example, to electrically lock out a water valve so water cannot be
turned on until the Extend-A-Gun RC is fully extended. When
configured for Extend-A-Gun RC "Extended", the USER relay will
be energized when the Extend-A-Gun RC is in the extended
position.
The Extend-A-Gun RC control box includes a cable that is pre-connected to the internal relays for easier access and to prevent the
waterproof seal from being damaged from improper re-installation of the lid. The 6-conductor wire and receptacle includes a Deutsch
DT06-6S-P012 6-position plug. There are easily removable sealing plugs inserted into each wire position to prevent water from entering
the connector when there is no wire inserted into the connector position. Use size 16 contacts for all positions. Maximum allowed current
draw through relay contacts is 10 amps. The connector pin configuration is shown as viewed from the wire side of the 6-position plug.
