Description
1. There are 4 thermocouple inputs on the temperature card labeled as TC1A, TC1B,
TC2A, TC2B. If a dual thermocouple is used make sure it is either paired between TC1A
and TC1B or between TC2A and TC2B.
Don't use a grounded thermocouple. They are not supported.
Only use type K thermocouples.
Yellow wire goes to the positive terminal. Red wire goes to the negative board terminal.
Do not parallel a single thermocouple by daisy chaining two thermocouple inputs
together. Doing this may give you a cross wiring error. Use a proper dual thermocouple
or change the input to a single in the settings.
The PFRN port on the temperature module is a power receiver. It will need to be
connected to a BMS controller PFRN port or a network card depending on the
installation.
Description
It is suggested to keep thermocouple lengths below 50 feet with a maximum run length
of 100 feet.
Up to 250 feet.
Indication
Solid green when there is a link or off without a link.
If the link LED is not solid green check the PFRN wiring.
Solid blue when the port is powered or off if not powered.
If the power LED is not solid blue check the PFRN wiring and the host card power (switch
or BMS depending on the install).
The fault LEDs will turn red if an input is open or cross wired or if there is a mismatch
between two dual inputs.
If the inputs are configured as singles and the thermocouples do not match the LEDs may
turn on, this is normal. The LEDs are indicating that the two inputs are configured as
singles and do not match, it has no effect on the system otherwise.
