Number Name and Appearance
Description
1) RUN
LED
Indicates the operating status of the Q62HLC.
On :
Operating
normally.
Off
: 5V power switched off, a watchdog timer error
occurred, or changing online module is allowed.
2) ERR.
LED
Indicates the error status of the Q62HLC.
On
: Hardware fault (Includes the case of cold junction
temperature compensation resistance is not
connected)
Flicker : Write data error occurrence
At auto turning error completion
Off :
Operating
normally.
3) ALM
LED
Indicates the alarm status of the Q62HLC.
On
: Alarm occurrence
Flicker : Process value (PV) is outside the measured
temperature range.
Loop wire break was detected.
Sensor is not connected. *1
Off
: No alarm occurrence
4) Terminal
block
Terminal blocks are used for various sensor input, current
output and external power supply input.
5)
Cold junction
temperature
compensation resistor
Used for Cold junction temperature compensation.
6)
FG terminal
For frame ground.
*1: The detection may not be made depending on the input range to use. Refer to
Section 2.4 for details.
