View information for the components of the units in the group:
Input and output contact states — open or closed.
Active power source (ACRC500 and ACRP500 cooling units only) — the power source
supplying power to the unit, A or B.
Rack inlet sensors — the temperature of the air at the sensors.
Filter differential pressure — the difference in pressure on either side of the air filter.
Containment differential pressure — RACS or HACS configurations only. The difference in
pressure between the front of the unit and the rear of the unit. This value affects fan speed control.
Humidifier current (ACRP100 and ACRP500 cooling units only) — the current draw from the
humidifier canister.
Humidifier water conductivity (ACRP100 and ACRP500 cooling units only) — the conductivity
of the water in the humidifier canister.
Suction pressure (ACRD500 and ACRP100 cooling units only) — the pressure at the compressor
inlet.
Discharge pressure (ACRD500 and ACRP100 cooling units only) — the pressure at the
compressor outlet.
Fluid valve position (ACRC500 and ACRP500 cooling units only) — how much the valve is
opened, as a percentage of the fully open position .
Fluid flow (ACRC500 and ACRP500 cooling units only) — the volume of fluid that is flowing
through the unit.
Entering and leaving fluid temperature (ACRC500 and ACRP500 cooling units only) — the
temperature of the fluid as it enters and as it leaves the unit.
