Description and cause
After the inter-module simultaneous temperature rise
function was started (Y1 was turned ON), the slave
temperature control modules cannot receive data from the
master temperature control module.
A hardware failure has occurred in the module.
Corrective action
Check that each module has been properly connected,
and turn ON the power supply again or reset the CPU
module.
• Check that the terminal block or the cold junction
temperature compensation resistor has not been
disconnected or loose.
• Power OFF and ON the module.
When the same error occurs again, the possible cause is
a module failure. Please contact your local Mitsubishi
Electric sales office or representative.
