Press display switch, and or will be displayed.
(1) If the following is displayed when
the display switch is pressed,
• indicates wire breakage
of storage temperature sensor.
• indicates short circuit of
storage temperature sensor. (when
temperature of sensor area is 0°C)
(2) For the resistance value of storage
temperature sensor, refer to Page 63.
∗
: Since the power supply is com-
monly used by TD sensor and
storage temperature sensor, the
power supply of storage tempera-
ture sensor will be cut off if the
power supply of TD sensor is
short-circuited. Therefore, wire
breakage indication is
displayed for storage temperature
sensor.
