Probable cause
Remedy
Settings
Selector settings for the input type of temperature
sensor are incorrect.
Correct the INPUT selector setting.
Celsius-Fahrenheit designation of the E5ZE is
incorrect.
Correct the FUNCTION switch setting.
The process value appears to be incorrect due to
the input shift setting.
E5ZE FUNCTION switch is not set correctly for
the E5ZD-SDL Setting Display Unit connected to
the E5ZE.
Set the input shift to 0.0.
Correct the FUNCTION switch setting.
Data setting unit is incorrect.
Change the program of the host device.
Program of the host device is incorrect.
Change the program of the host device.
Operation
Temperature sensor input terminals of the E5ZE
thermocouple input model have been
short-circuited.
Connect a thermocouple to the temperature
sensor input terminals.
Temperature sensor connected to the E5ZE has
been replaced or the switch or selector settings of
the E5ZE have been changed while the power is
ON.
Turn OFF the power to the E5ZE, and then turn
ON again.
Simple Method for Checking Temperature Sensors
Platinum Resistance Thermometer
1, 2, 3...
1. Connect a 100-
Ω
resistor between the A and B temperature sensor input
terminals and short-circuit the B terminals.
2. If the temperature sensed by the E5ZE is 0.0
°
C or 32.0
°
F, the E5ZE is oper-
ating normally.
Thermocouple
1, 2, 3...
1. Short-circuit the temperature sensor input terminals of the E5ZE.
2. If the E5ZE senses the temperature of the terminal block of the E5ZE, the
E5ZE is operating normally.
