Checking data connection
7.9.1 Checking control cables
The data/commands are communicated via control cables. Depending on the fitted
equipment, these should be connected and/or checked in accordance with the wiring
diagram attached to the unit connection box (see "Connecting control cables" on
page 63).
The yellow LED on the unit PCB signals power supply to the electronic components
(not with MATRIX 511).
•
If the LED is off, check the 230 V power supply on the unit.
7.9.2 Checking data connection
Data are communicated via a 2/4-wire data cable. This cable must be connected and/
or checked in accordance with the wiring diagram attached to the unit connection box
(see "Completing bus connection" on page 65).
Three LEDs on the unit printed circuit board signal the operating status of the unit.
Danger of electrical current!
Before correcting an error in the data connection, power down the entire plant.
Ensure that the unit is properly secured against subsequent switch-on at an appro-
priate point of the on-site power supply.

Error in electronics
De-energize PCB and wait for a short time. Power the
PCB on again. If the error message is still present, re-
place the PCB.
Flashes
Data bus interruption
Check the connection of the data cables and the setting
of the terminating resistors on all units.
