External Connections
• A voltage output (control output, for driving SSR) is not electrically insulated from the internal circuits. When using a grounding thermocouple,
do not connect any of the control output terminals to ground. If the control output terminals are connected to ground, errors will occur in the
measured temperature values as a result of leakage current.
Controllers
Note: Wire all voltage input terminals correctly. The Controller may fail if voltage input terminals are wired incorrectly.

The Temperature Controller is set for a K-type
thermocouple (input type = 5) by default. An input error
(s.err) will occur if the input type setting does not agree
with the temperature sensor. Check the input type.
