Temperature Controllers E5CSV 9
Error Displays and Causes
In addition to the alarm indicator, errors notification is provided on the display. Be sure to remove the cause of the error promptly.
Note: In models with an alarm, fff appears or flashes on the display to indicate that the temperature has exceeded the maximum display temperature and the output
is set according to the alarm mode. In the same way, --- appears or flashes on the display to indicate that the temperature has exceeded the minimum display
temperature and the output is set according to the alarm mode.
Sensor Error Displays and Causes
■ Thermocouple
Note: The room temperature is displayed if an input short-circuit occurs.
■ Platinum Resistance Thermometer
Note: The resistance value for platinum resistance thermometers is 100 Ω at 0° C and 140 Ω at 100° C.
Display status Cause Control output
PV displayed as
fff
The process value is higher than the control temperature range (overflow). Heating control (reverse operation): OFF
Cooling control (direct operation): ON
PV displayed as
---
The process value is lower than the control temperature range (underflow). Heating control (reverse operation): ON
Cooling control (direct operation): OFF
fff flashing (1)Thermocouple models and platinum resistance thermometer models:
The process value is higher than the overflow temperature, or a Sensor error has
occurred.
(2)Multi-input (Thermocouple/platinum resistance thermometer) models:
The process value is higher than the control temperature range or a Sensor error
has occurred.
OFF
--- flashing (1)Thermocouple and platinum resistance thermometer input:
The process value is lower than the underflow temperature, or a Sensor error has
occurred.
(2) Thermocouples: The polarity is reversed.
(3)Multi-input (Thermocouple/platinum resistance thermometer) models:
The process value is lower than the control temperature range or a Sensor error has
occurred.
OFF
e11 is
displayed
A memory error (E11) has occurred. Turn the power ON again. If the display remains
the same, the Controller must be repaired.
The control outputs and alarm outputs
turn OFF.
