The display provides alarms in plain text and the ER codes shown in the list. Use the arrow buttons to scroll through multiple alarms
displayed at the same time.
The fault memory stores the last 20 alarms for review, see chapter 7.6 "Parametrising the controller in the Customer menu" on page 42 .
Alarm causes can be eliminated by the operator or a specialist workshop. If this is not possible, contact the Reflex Customer Service.
Note!
Clearing of the cause must be confirmed by pressing the “Ack” button on the operator panel. All other alarms are
automatically reset as soon as the cause has been eliminated.
Note!
Floating contacts, setting in the Customer menu, see chapter 7.6 "Parametrising the controller in the Customer menu" on
