To Get The Tv-Psm's Serial Number; To Replace The Tv-Psm's Fuses - Carrier TruVu ChillerVu Installation And Startup Manual

To get the TV-PSM's serial number

If you need the controller's serial number when troubleshooting, the number is on:
•
A Module Status report (Modstat).
•
A laser-etched number and QR code on the circuit board inside the controller.
•
Some controllers have a sticker on the front with the serial number, MAC address, and a QR code.
See To get a Module Status report (page 50).

To replace the TV-PSM's fuses

The TV-PSM has 2 fuses:
Symptoms of a blown fuse:
•
TV-PSM's power fuse—The controller's
•
I/O bus edge connector fuse—The
connector.
NOTE If the TV-PSM's power fuse blows but not the I/O bus edge connector fuse, the TV-PSM will be off but not
the downstream expanders.
If you suspect a fuse is blown, remove the fuse as described below, and use a multimeter to check it. If the fuse is
blown, try to determine why it blew before you replace it. Check the power wiring polarity of the TV-PSM and any
other devices that share the power supply. Use the same polarity for all of them.
The fuses are fast-acting, 5mm x 20mm glass fuses that you can purchase from one of the following vendors:
