Close timer start Valve Position : The user has to set the valve position at which this Timer
mode should go on for Close command.
Close ON time : This parameter decides the amount of time (in s) the actuator runs in Close
direction before shutting off for Close OFF time (in s). This continues to happen until the
respective limit switch is hit (unless the switch is bypassed).
Close OFF time : This parameter decides the amount of time (in s) the actuator shuts off
before running in open direction for Open ON time (in s). This continues to happen until the
respective limit switch is hit (unless the switch is bypassed).

REAL TIME CLOCK (RTC)
This module has a Real time clock that is used to obtain the time-stamp for Event logging. The RTC
can be configured by Auma Utility Software or by manually setting the RTC in Program Mode
settings. The RTC is powered by a Super Capacitor when the power is off which is another added
feature of this module. The Super Capacitor takes about 2 hours to charge and can supply power
