7.2.8 Flue Pressure Units and Value
The 9060Z transmitter is capable of fixed or variable input pressure compensation in the calculation of
oxygen from ‐1 Atm to +3 Atm. If the probe is running in a pressurized environment this value should
be set to allow for accurate oxygen measurement. If the flue pressure is constant select 'Fixed" in this
function and set the pressure units and value in the proceeding menus. If the pressure varies, select
"Variable", and connect a pressure transducer to terminals 24 & 25. (See section 4.23). Set the range
of the transducer using a zero and span value in the commissioning menus.
7.2.9 Temperature Units
The display on the transmitter can be changed to show temperature in either Celsius or Fahrenheit
scales.
7.2.10 Calibration Freezes Outputs
During gas calibration checks it may be required that the analogue outputs remain frozen at their last
reading. When cal freezes is enabled both analogue outputs remain frozen until the entire calibration
cycle has completed.
7.2.11 Solenoid 1 & 2 Operation
The two solenoid outputs can be individually configured to perform gas calibration check or probe
purge.
Some of the menus between functions 22 to 28 (31 to 37) will not appear depending on what has
been selected in function #20 and #21 (29 and 30).
7.2.12 Solenoid 1 & 2 Automatic / Manual
When set to automatic the solenoid will perform a pre‐programmed gas calibration or purge cycle.
When set to manual the solenoid is controlled directly from the corresponding key on the front of the
case. When set to automatic the calibration check or the purge cycle can be started by pressing the
corresponding key on the front of the case. It can be stopped by pressing the same key again.
7.2.13 Solenoid 1 & 2 Start Time
For automatic gas calibration checking or purge events a start time is specified to allow precise control
over the timing of such events. Starting at this specified time, the next gas calibration or purge event
will occur in successive intervals from this time.
7.2.14 Solenoid 1 & 2 Period
This option specifies the period between automatic gas calibration or purge events. For periods less
than 24 hours the period is divisible into 24 hours forcing scheduling of events to occur at the same
time each day between 1 minute and 7 days.
The ‘No Timed Operation’ option accessible by scrolling the option below 1 minute allows for pre‐
configured solenoid cycles to be triggered manually via the keypad, but without the automatic
scheduling.
7.2.15 Solenoid 1 & 2 Duration
Duration of time that an automatic gas calibration or purge event energizes the solenoid
