KMC BAC-10000 manual Wiring Issues, Relay External Does Not Work

•If the firmware has just been upgraded, firm- ware for the wrong model type may have been installed (e.g., BAC-1xx63 firmware accidentally installed in a model BAC-1xx36). In the About menu, ASV may simply read “CUSTOM” instead of something like “BAC_1xx36 R1.1.0.5” as it normally would have done. If so, repeat the firm- ware upgrade and ensure that the correct type of firmware is selected for the connected model.

NOTE: ASV in the About menu will also show CUSTOM if any built-in Control Basic program (1–5) is not running or has auto- run disabled.

Wiring Issues

CAUTION

Do not mistakenly connect 24 VAC to an analog output ground. This is not the same as a relay’s switched common. See the backplate’s terminal label for the correct terminal.

CAUTION

Relays are for Class-2 voltages (24 VAC) only. Do not connect line voltage to the relays!

•Remove the FlexStat from the backplate and inspect the terminals for loose or shorted wires.

•Use a voltmeter and ohmmeter to check the terminals for expected values. See the illustration below and the the Connections and Wiring sec- tion of the relevant BAC-10000 Series Installation Guide.

NOTE: Voltage on the BACnet MS/TP terminals changes according to the signals (passing of the token) between controllers on the network. No voltage indicates a bad connection or simply no active network.

•Check the wiring at the connected devices.
