8.2.8 HEATER SSR FAULT CORRECTION
In the event of one of the heater solid state relays (SSR) failing in single probe mode, the heater drive output can be swapped to the HEATER 2 output. Select “Heater 1<‐> Heater 2”.
If you are running in dual probe mode but not using the calibration gas or purge solenoid outputs the solenoid outputs can be swapped to the 2 heater outputs. Select “Heaters <‐> CalPurge”. The default setting is “Normal”.
8.2.9 SSR FAIL PROTECTION
The transmitter continuously monitors the high voltage outputs on the solid state relays that power the probe and purge/cal solenoids. If it detects that any solenoids are not switching off correctly then it mechanically isolates all high voltage outputs in order to protect the instrument. This feature can be switched off by setting the SSR fail protection to disabled.
