WARNING! In the event of an apparent malfunction in
the braking or any other systems during RF compatibility
checks, the SCG22 installation should be rendered
inoperative and the vehicle manufacturer should be
contacted before any further use is made of the SCG22
installation. Unqualified persons should not attempt to
modify these units in any way.
RF Compatibility Checks
On completion of the installation, the following checks must be
carried out if the vehicle is equipped with electronic anti-skid,
electronic ignition or engine management systems.
The transmitter should be operated only for the time required to make
an observation. Ideally these checks should be performed on the TETRA
system. If this is not possible, perform the checks in DMO.
An assistant will be required for the following checks:
1. With the vehicle stationary and the engine running at fast idle, operate
the transmitter. Check that the brake lights do not illuminate and that
the engine continues to run normally, i.e., with no surging or cutting
out.
2. Operate the brake pedal, key the transmitter and check that the brake
lights do not extinguish.
3. Put the vehicle into motion at a speed of 15 – 25 km/h (10 –15 mph),
key the transmitter and operate the brake pedal simultaneously.
Check that the braking action is normal and that the engine does not
surge or cut out.
Connector Sealing
To maintain the product's IP54 rating to protect against dust and moisture
ingress, the SCG22 must be fitted with connector seals. Any unused
connectors must be fitted with a sealing bung or cap. An IP54 Sealing Kit
is provided with the SCG22 consisting of all the sealing parts required.
D-Connectors
Other Connectors
• If the SMA or SMC sockets
are unused, fit the cover seals
provided
• If the RJ45 socket is unused, fit the bung provided, observing the
correct orientation
1. Carefully peel the adhesive
backing from a D-sub seal.
2. Fit the seal over a D-connector in the correct orientation and press
firmly to attach.
3. If the D-connector is currently unused, fit an appropriate seal bung
(male or female) fully into the seal housing.
