External Connections - Omron E5CWL Connections

External Connections

 A voltage output (control output) is not electrically insulated from the internal circuits. When using a grounding thermocouple, do not connect
any of the control output terminals to ground. If the control output terminals are connected to ground, errors will occur in the measured
temperature values as a result of leakage current.

(1) Display No. 1 Displays the process value (PV) or parameter. For the E5CSL/E5EWL,
the set point or parameter setting is also displayed.
(2) Display No. 2 Displays the set point (SP) or parameter setting.
(3) Deviation Show the relation between the process value and the set point.
Indicators Lit: The process value is more than 5°C/°F higher than the set point.
Lit: The process value is more than 5°C/°F lower than the set point.
Lit: The process value is within 5°C/°F of the set point.
The relevant deviation indicator will flash during autotuning.
(4) SP Lit while the set point is displayed on display No. 1 (E5CSL only).
(5) ALM Lit while the alarm is ON. Not lit while the alarm is OFF.
(6) OUT Lit while the control output is ON. Not lit while the control output is
OFF.
(7) STOP Not lit during operation. Lit while operation is stopped.
(8) O
Level Key: Changes the setting level.
(9) M
Mode Key: Changes the parameter within the setting level.
