8. Secure the Junction Box Cable to TB1 and TB2 as shown in Figure 2-14.
9. Tighten the cable grip ensuring there is adequate slack inside the control box.
2.6.2.3 Wire Vehicle Interlock on Sensor
The Night Scan Lite and Inflexion HD is designed to allow for integration into vehicle safety
circuitry to eliminate the possibility of driving with the mast extended. Usage shall be used to
comply with various safety standards such as NFPA-1901. Possible Vehicle Interlock systems
include a customer-supplied flashing warning lamp in the cab, or wiring into the parking brake or
transmission circuit. The customer is responsible for determining which system works best for
the specific application. The installer shall ensure that voltage is only supplied to the mast
system when the vehicle is stationary.
Vehicle safety circuitry interfaces with the Mast System through a dedicated proximity sensor
located on the mast base. This sensor and associated customer provided wiring are completely
independent from the mast control system and no wiring connections are made within the mast
control box or junction box. The interlock circuit should be wired directly to the sensor.
Sensor Adjustment Procedure:
The proximity sensor is located on the base (Figure 2-15). It is factory set to the proper distance
from the moving base section. Over time, it may be necessary to adjust the sensor distance if it
is no longer sensing the base section when nested or too close to the moving base section. The
sensor should never be allowed to contact the base section. To achieve this, with the mast
nested and the interlock circuit powered loosen the nut and move the sensor to the location
when the LED indicator light activates (approximately 6 mm from the base section). From that
