9.592 SPX-Etsiline-CommPact

This page describes the device driver and the device window for SPXFLOW Etsiline CommPact dehydrator.

For SW releases earlier than 1.02 use SPX-Etsiline-CommPact-1-01 device driver.

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- Meter readings.
• --- The faults page.
• --- The device info page.
• --- The maintenance page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device as well as to allow proper alarm monitoring.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• readBackDelay --- Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized or a proved preset value which should not be changed under normal circumstances.

• pressureLowLevel --- Defines the low pressure operation point .

• pressureHighLevel --- Defines the high pressure operation point.

• pressureLowAlarm --- Defines the lower limit for the device pressure in mBar which triggers the low pressure fault.

• pressureHighAlarm --- Defines the upper limit for the device pressure in mBar which triggers the high pressure fault.

• humidityAlarm --- Defines the upper limit for the device humidity in percent which triggers the high humidity fault. Default humidity alarm is set on 7% RH, which is a dew point of -15°C at 22°C ambient.

• alarmDelay --- Defines the delay time for alarms in seconds. When an alarm restores within de delay time, no alarm signal will be given.

• pressureHysteresis --- Defines the alarm pressure hysteresis for low and high pressure alarms between 5mBar and 250mBar.

• runtimeAlarm --- Defines the compressor runtime alarm threshold in minutes. When the compressor runs more than the set running hours, a run time alarm is given.

• humidityEnable --- Enables monitoring of a humidity sensor if supported by the device .

• dewpointEnable --- Enables monitoring of the dew point if supported by the device.
