This item from the Con figuration info menu allows to view the configured alarm thresholds,

4.3.3 Relays failsafe modes
The safety mode of a relay defines its status when it is at rest:
Not in failsafe mode: the relay is not powered at rest.
Failsafe mode: the relay is powered at rest.
The failsafe mode of an alarm relay is unset by default. The failsafe mode of each alarm
relay is independently configurable.
By default, all relays are 'Not failsafe,' except for the fault relay which is always 'Failsafe.'
