7.2.10 Temperature Units
Options: Celsius or Fahrenheit
Default:
Celsius
The display on the transmitter can be changed to show temperature scaled in either Celsius or Fahrenheit.
7.2.11 Calibration Freezes Outputs
Options: Enabled or Disabled
Default:
Enabled
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.
7.2.12 Solenoid 1 & 2 Operation
Options: Disabled / Calibration Gas / Purge
Default:
Disabled
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).
7.2.13 Solenoid 1 & 2 Automatic / Manual
Options: Manual or Automatic
Default:
Manual
When set to automatic the solenoid will perform a pre-programmed gas calibration or purge cycle when the
function is triggered. When set to manual the solenoid is controlled purely from the corresponding button on
the front of the case.
When set to automatic the calibration check or the purge cycle can be started by pressing the corresponding
button on the front of the case. It can be stopped by pressing the same button again.
The Commissioning Menu functions #24 to #31 relating to Solenoid 1 will vary depending on the solenoid
mode of operation selected in function #23 & #24. Likewise, the Commissioning Menu functions #33 to #40
relative to Solenoid 2 will vary depending on the solenoid mode of operation selected in function #32 & #34.
7.2.14 Solenoid 1 & 2 Start Time
Options: 00:00 to 23:45 in 15 minute increments
Default:
00:00 (midnight)
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.
7.2.15 Solenoid 1 & 2 Period
Options: No Timered
1 to 5 Minutes in 1-minute increments
10 / 15 / 20 / 30 Minutes
1 / 2 /3 / 4 / 6 / 8 / 12 Hours
1 to 7 Days in 1-day increments
Default:
1 Hour
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' option accessible by scrolling the option below 1 minute allows for pre-configured solenoid
cycles that are only triggered manually via the keypad.
