Settings/setup System 2020 XT 5.8.4 Alarm output as relay action The relay outputs of the IQ S can be configured so a relay ENSOR action is triggered when an alarm event occurs (Open or Close). For this the Alarm contact function must be set for the relay output in the Settings of outputs and links.
System 2020 XT Settings/setup System settings System settings include: Change password (see section 5.9.1). Language (see section 5.1) Date/Time (see section 5.9.2) Loc. altitude (see section 5.9.3) 5.9.1 Changing the password A password protects the system settings against inadvertent changes. The password must always be entered in order to change the release of the settings.
Settings/setup System 2020 XT Note Forgotten the password? You can display the valid password on the screen (see section 11.1). 5.9.2 Setting the date and time The real time clock is used for the display of date and time in the mea- sured value display and in log book entries.
System 2020 XT Settings/setup Note The clock in the MIQ/MC bridges periods of power failure of up to 24 hours. After a longer power failure, the clock starts precisely at the time of the failure. A message and an entry in the log book provide informa- tion on the power failure and the necessity for resetting the clock.

System 2020 XT What to do if ... What to do if ... Information on errors Log book The IQ S system performs a comprehensive cyclical self ENSOR test during operation. While doing so, the system identifies all states that deviate from normal operation and enters corresponding mes- sages in the log book (information or error message).
