Note1: Extension of Standard Sensor Loom
The length of the standard loom supplied for connection of the PLM to a sensor
is 2.5m. Longer looms are available from MoTeC by request.
It is not recommended that the loom is extended by using a standard serial
cable. These are unable to supply the current required by the sensor. If an
extension is made, the wire thickness must be at least 20 gauge.
Note 2: Power Supply Current
If using a power supply other than the vehicle battery, start-up current for the
sensor is up to 5A, though operating current is much lower than this, 0.5 – 1
Amps, depending on exhaust gas temperature.
