Sets the Full Scale De ection value for the 4 – 20mA Analogue Output of the Oxygen sensor(s).
Sets the address for the generator when communicating on a network via the RS485 MODBUS port.
Address range is 1 – 32
When enabled the Oxygen alarm is over-ridden.
0 = Over-ride disabled, 1 = Override Enabled [OVR]
When enabled the bed cleaning cycles will run whenever the generator is powered up, comes out of
standby mode and economy mode.
0 = Disabled, 1 = Enabled
Sets the mode of control for the generator
1 = Local Start / Stop control, 2 = Remote Start / Stop control via the digital input, 3= Remote
communication
Outlet oxygen sensor calibration menu.
Enables the economy mode.
0 = Disabled, 1 = Enabled
Sets the purity level at which an oxygen fault is initiated.
Default Settings:
% Generators - 0.05% above the selected production purity.
ppm Generators - 5ppm above the selected production purity.
If the purity level exceeds the oxygen alarm level for a period longer
When enabled the actuation of the Stop control will generate an alarm.
0 = Disabled, 1 = Enabled
If the purity level exceeds the oxygen alarm level for a period longer than the alarm delay, the oxygen
alarm will be activated and the gas will be vented to atmosphere.
Delay Range = 0 – 600 Seconds, Default = 60 Seconds
