Low Level and Empty Level Indicators
The Tandem Run screen has low material level and
empty material level indicators. You can enable or
disable the sensors for these on
Pump Screen 2 -
Drum Settings
. These monitor the material
level in the drums.
The indicators normally show as green. When a low
level sensor on the ram is activated because material in
the drum is low, the top indicator for the pump turns red
and an error symbol appears next to the pump.
When an empty level sensor is activated on the ram, the
bottom indicator for the pump turns red and the error
symbol changes to the one selected for the empty level
sensor.
