Set Relay State - 0x5F
This command allows you to configure the relay states. The relays are normally de-energized,
and can be configured to operate in the energized fail-safe condition. When the relays are
latched, they are cleared by operator intervention. Non-latching relays are cleared automatically
once the concentration decreases below the alarm level threshold, or the fault is corrected
without operator intervention.
