Ally types have colored connection points. Other connection point types depend on the particular variant.
Important information for proper use:
– The digital input is not electrically isolated from internal circuits, so it must be insulated if it is connected
to another circuit.
– Make sure that the connection polarity of the temperature sensor or analog input is correct.
– Make sure the polarity of the power supply is correct.
–
Do not swap the output and input terminals.
–
For thermocouple sensors, use a compensation cable with the same specifications as the input sensors.
Using an extension cord of different specifications and/or materials makes temperature sensing less
accurate. For more reliable operation, choosing a high-grade compensation cable is recommended.
–
Do not place sensor wires near AC wires.
– Do not attach communication cables to the AC power cord. Use only twisted-pair wires for communication
cabling. The length of the communication cable must not exceed 800 meters.
5. PROGRAMMING
5.1 PARTS AND DISPLAY
The seven-segment displays show the measured
(Process
Value, PV)
and set values
(SV)
in regular operation, while
in other modes, they show the corresponding text signals
and values according to the current status of programming
and setting. Use the 4 buttons to operate the menu system
and perform programming.
