Schedule A
The setting CONTACT I/P=FOR A/B enables the digital input to switch back and forth between
schedule A and B.
Schedule A is active if the digital input is open. The possible timing settings are limited with
MAX ADV A and MAX RET A to values between 25° BTDC and 5° BTDC. With a potentiometer
setting of 20 BTDC and a signal of 4 mA via the 4-20 mA input, the above configuration example
