Emerson MODBUS 485 Manuel D’Utilisation

Compressor Capacity Control State

Compressor capacity control state. When 'ON', the cooling capacity of the 

compressor has been reduced.

Compressor Capacity Reduced

Compressor capacity has been reduced.

Compressor High Head Pressure - Event 

Control

Enable/disable the activation of the [Compressor High Head Pressure] event. If 

set to 'disabled', the event will not be annunciated. This implies that the event 

will not be placed in any active event list or in any event history list.

Compressor High Head Pressure - Event 

Type

The event type for the [Compressor High Head Pressure] event.

Compressor High Head Pressure

Compressor is shut down due to high head pressure.

Compressor High Pressure Transducer 

Issue

Compressor high pressure transducer is disconnected or the signal is out of 

range.

Compressor Hours Exceeded

[Compressor Hours] has exceeded [Compressor Hours Threshold].

Compressor Hours Threshold

Threshold value used in the [Compressor Hours Exceeded] event.

Compressor Hours

Operating hours for compressor since last reset of this value.  If operating hours 

exceeds 32,000, this client will continue to display 32,000, but the iCOM display 

will show the actual value.

Compressor Lockout

Enable/disable the use of the compressor.

Compressor Low Differential Pressure 

Lockout

Compressor exceeded maximum startup attempts due to low differential 

pressure. Compressor is shutdown and has been disabled.

Compressor Low Pressure Transducer 

Issue

Compressor low pressure transducer is disconnected or the signal is out of 

range.

Compressor Low Suction Pressure - 

Event Control

Enable/disable the activation of the [Compressor Low Suction Pressure] event. 

If set to 'disabled', the event will not be annunciated. This implies that the event 

will not be placed in any active event list or in any event history list.

Compressor Low Suction Pressure - 

Event Type

The event type for the [Compressor Low Suction Pressure] event.

Compressor Low Suction Pressure

Compressor is shut down due to low suction pressure.

Compressor Pump Down Issue - Event 

Control

Enable/disable the activation of the [Compressor Pump Down Issue] event. If 

set to 'disabled', the event will not be annunciated. This implies that the event 

will not be placed in any active event list or in any event history list.

Compressor Pump Down Issue - Event 

Type

The event type for the [Compressor Pump Down Issue] event.

Compressor Pump Down Issue

Unable to pump down suction-side pressure during compressor shutdown.

Compressor Short Cycle - Event Control

Enable/disable the activation of the [Compressor Short Cycle] event. If set to 

'disabled', the event will not be annunciated. This implies that the event will not 

be placed in any active event list or in any event history list.

Compressor Short Cycle - Event Type

The event type for the [Compressor Short Cycle] event.

Compressor Short Cycle

Compressor short cycle. A short cycle is defined as turning on and off a number 

of times over a set time period.

Compressor Superheat Over Threshold

Compressor discharge refrigerant superheat temperature has exceeded an 

upper threshold.

Compressor Thermal Overload - Event 

Control

Enable/disable the activation of the [Compressor Thermal Overload] event. If set 

to 'disabled', the event will not be annunciated. This implies that the event will 

not be placed in any active event list or in any event history list.

Compressor Thermal Overload - Event 

Type

The event type for the [Compressor Thermal Overload] event.

Compressor Thermal Overload

Compressor is shut down due to thermal overload.

Compressor Utilization

Present compressor utilization expressed as a percentage of the maximum 

rated capacity.
