E5EX–H E5EX–H Operation NOTICE: Always turn off the power supply to the Temperature Controller before changing any switch settings. Accessing Switches and Selectors Before supplying power to the Temperature Controller, the selectors and switches shown below must be set to specify the temperature sensor, functions, and alarm mode.

E5EX–H E5EX–H Standby Sequence Alarm functions with standby sequence suppress nuisance alarms when the controller is first powered up. As shown in the temperature charts at right, the alarm output is suppressed until the temperature exceeds the alarm band or alarm limit one time. Protection Switch (SW101, PROTECT) When the protection switch is set to the ON position, the level key, up and down keys, and auto-tuning key will not operated.
