7.2.16 Solenoid 1 & 2 Post Freeze
Duration of time the transmitter waits before resuming live readings following a gas calibration or
purge event. (See also chapter 7.2.10)
7.2.17 Oxygen Content Calibration Gas 1 & 2
When configured as a gas calibration check solenoid this value specifies the oxygen content of the
calibration gas.
7.2.18 Maximum Calibration Gas 1 & 2 Positive / Negative Error
Specifies the maximum positive & negative error levels used during the gas calibration check.
If the difference between the specified oxygen content and the measured process gas exceed these
thresholds, a gas calibration error alarm will be triggered immediately.
7.2.19 Process Alarms
The oxygen measurements are continuously monitored by the transmitter for process alarm
conditions (Process alarms must be enabled in the Set up menu). The limits and the alarm time delays
are configurable for the Very Low Oxygen alarm, Low Oxygen alarm, High Oxygen alarm and the
Oxygen Deviation alarm.
7.2.20 Alarm Relay 1, 2 and 3 Function
There are 3 user configurable alarm relays. Any of the 3 relays can be configured to be triggered on
the following alarm conditions. In addition, any of the alarm conditions that are disabled from the
common alarm relay can also be configured to trigger these 3 relays. Multiple selections can be made.
Process Alarms
Oxygen 1 Low Probe 1 Temperature Low
Oxygen 2 Low ** Probe 2 Temperature Low **
Oxygen 1 Very Low Calibration 1 In Progress
Oxygen 2 Very Low ** Calibration 2 In Progress **
Oxygen 1 High
Purge 1 In Progress
Oxygen 2 High ** Purge 2 In Progress **
Oxygen Deviation
7.2.21 Common Alarm Relay Function
