3.6. System failure
In this case, the safety function has failed (see chapter 3.7). Two separate errors
have occurred in the WinPro
®
/ MX62.
The system failure is only indicated after the system has tried to maintain the
measuring function by resetting. During this time, the system operates as if it is
in start-up mode though the outputs of the relay modules are not reset.
Depending on the configuration of the system, there can be a time delay of up to
90 s between error occurrence and indication.
ATTENTION!
The gas detection system WinPro
®
/ MX62 differentiates the faults of the
complete system from those of a specific channel (chapter 3.3.3).
When configuring safety control devices to be connected to the system, please
bear in mind that a system error does not automatically lead to activation of all
relay outputs for channel malfunctions. In this case, the switch position of the
relay
System failure has to be taken in account.
