Wiring Examples - Panasonic KT9 Instruction Manual

Notice
• The terminal block of KT9 series is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened
with the terminal screw.
• Dotted lines show options.
• If A2 (option) and Heater burnout alarm (option) are applied together, use
terminals 12-13 for A2, and 9-10 for the Heater burnout alarm.
• If the Heating/Cooling control (option) and Heater burnout alarm (option) are
applied together, use terminals 9-10 for the Heating/Cooling control, and 12-13
for the Heater burnout alarm.
• When only Heater burnout alarm option is applied, use terminals 9 and 10.

4.2 Wiring examples

Notice
• To extend a thermocouple's lead wire, be sure to use a compensating lead wire in
accordance with the sensor input specification. (If any other compensating lead wire
is used, a temperature indication error may be caused.)
• Use the 3-wire RTD according to the sensor input specifications of this controller.
• This controller does not have built-in power switch, circuit breaker or fuse.
It is necessary to install them in the circuit externally, near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC).
• When using a relay contact output type, use a relay externally according to the
capacity of the load to protect the built-in relay contact.
• When wiring, keep the input wire (Thermocouple, RTD, etc.) away from AC sources
or load wires to avoid external interference.
• Use a thick wire (1.25 to 2.0mm
