Shared Parameter Settings Section 4-6
Setting the Over-temperature Output Threshold: TMP (Temperature)
The Over-Temperature Output Threshold Setting (TMP) will be displayed if the
Up (SEL) Key ( ) is pressed from the Maintenance Forecast Monitor Detec-
tion Threshold Setting (LFE).
Note • If the temperature exceeds the threshold value for more than 1 s, the
over-temperature output (TMP) photoswitch output will turn OFF and the
seven-segment display will alternate between error code A30 and the
measured temperature.
• The error display and over-temperature output are reset automatically
after the temperature falls and remains below the threshold value minus
3°C for longer than 5 s.
• The over-temperature output (TMP) operates independently of the other
external outputs. This output can be received as a normally closed output
and used to start an exhaust fan or air conditioner to reduce the tempera-
ture in the control panel.

This parameter sets the over-temperature output threshold.
Press the Key to display the over-temperature out-
put threshold (SV). The SV can be changed by press-
ing the and Keys.
The setting range is 25°C to 90°C
Change the SV with the and Keys.
• The S8AS will automatically return to the TMP dis-
play if no key is pressed within 3 s.
• If the or Key is pressed for more than 2 s, the
SV will change in 10°C increments instead of 1°C
increments.
When the Key is pressed, the SV display will flash.
When the flashing stops, the new setting will be saved
and the S8AS will return to TMP display.
If you want to confirm the new setting, press the
Key again from the TMP display.
