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.
