WGA 01
Oil- petrol- grease alarm type ema signal WGA 01
General information
Installation is only permitted by authorised
and competent personnel and all parts of the
Installation Manual must adhered to.
Mounting
The ES4 capacitance sensor should be fixed
at a height 150 mm below the constant water
level in the separator, and must be immersed
in water to prevent an alarm being initiated.
lf a 1” cable gland is used for the mounting in
the tank make sure that the cable is securely
tightened. Make sure that the sensor is easy
to lift out of the tank in order to protect the
probe when emptying the tank.
The cable should be mechanically protected.
lf the WGA 01 unit is used for oil surface AND
high level alarm functions, make sure the R6
thermistor probe is mounted at the correct
level in the separator tank.
Checking
Ensure the sensors are mounted at the cor-
rect heights wihin the separator. (lf in doubt
this informaton should be obtained from
the separator manufacturer or supplier, it
is not the responsibility of the alarm system
manufacturer).
Make sure that the cable glands are properly
tightened.
Make sure that cables are connected
according to the connection scheme and that
the cable polarity is correct.
