2.7 RELAY BOARD
The dry contacts on the optional relay board make it possible to remotely view
the states of the stages that are activated and all the fault states on the unit.
● A 230 V ±10% power supply must be provided for the relay board.
● Connect terminal block J1 (1-2) on each relay board to terminal block J10 on
the motherboard.
● The board has a relay fault which will activate in the event of incorrect wiring.

3 ACCESS LEVELS
Xtraconnect 2 features three parameter access levels:
- Level 1: Users.
- Level 2: Technicians/Maintenance.
- Level 3: CIAT Technicians (full access)
3.1 Selecting an authorised access level
Authorised access levels are selected in menu 14 (ACC. LEVEL SELECT.). The following screen appears:
- Level 3 provides automatic access to all levels (CIAT technicians).
- Level 2 provides access to levels 1 and 2 only (Technicians/Maintenance and CIAT technicians).
- Level 1 provides access to level 1 only (all users).
3.2 Accessing the various access levels
3.2.1 Restricting access to level 1 only
- Access level 2 is the default access level.
- If you are in a higher level and you want to restrict access to level 1 only, simultaneously hold down the ESC and OK buttons for 10 seconds.
- No password is needed to access level 1. The setpoint adjustment range is +or –5 K lower than in the higher access levels.
- The restriction messages remain displayed in access level 1. Operating messages in optimised mode are visible only in access level 2 and up.
- Restriction of access to level 1 only is stored in memory in the event of a mains power failure.
3.2.2 Access to level 2:
A numeric code must be entered to access level 2:
- The following menu for entering this code appears when level 2 is selected.
