6.5.7 OUTPUTS RETRANS
Enables the water level to be remotely sensed, recorded or displayed.
0 or 4 mA
This menu enables the user to choose between a 0 or 4 mA minimum setting. Default 4 mA.
(4 mA is used so that a 0 mA signal will act as an indication of a fault).
SET
4 mA and 20 mA retransmission levels are set as a percentage of the gauge glass, normally
4 mA = 0% and 20 mA = 100, though this can be changed if required. Setting a 4 mA to a
percentage level higher than the 20 mA setting will invert the transmitted. e.g. rising water
level, with reducing current.
CHECK
Enables the user to make adjustments to the 4 mA and 20 mA settings, to calibrate to a
DVM reading, for example.
6.5.8 OUTPUTS POSITION
Outputs a signal to a 4-20 mA positioner.
0 or 4 mA
This menu enables the user to choose between a 0 or 4 mA minimum setting. Default 4 mA.
(4 mA is used so that a 0 mA signal will act as an indication of a fault).
SET
Enables the rescaling of the 4-20 mA signal to the positioner. Normally 4 mA = 0% and
20 mA = 100% of the required valve position. Setting 4 mA to 100% and 20 mA to 0% will
invert the transmitted signal.
CHECK
Enables the user to make adjustments to the 4 mA and 20 mA settings, to calibrate to a DVM
reading, for example.
6.5.9 OUTPUTS COMMS
Address is set to 1 unless there are other units on the same system.
