This window is used to set the digital outputs of the pulse isolator to a required state for loop testing purposes. The pulse output and the alarm output can be switched on, switched off or pulsed for few hundred milliseconds. The pulse output can also generate 50% ratio frequency signal with value configurable between 63 to 10000Hz. Also the red LED <STS> can be tested.
This should only be activated while the process variable is not monitored by a closed-loop control system.
