In the parameter display of a timing relay you can change the
mode, the time base, the time setpoint 1, time setpoint 2 (if
necessary) and the enable of the parameter display.
Parameter display in RUN mode:
Retention
Timing relays can be run with retentive actual values. Select
the number of retentive timing relays in the SYSTEM…
J
RETENTION… menu. T7, T8, T13 to T16 can be used as
retentive timing relays.
If a timing relay is retentive, the actual value is retained when
the operating mode is changed from RUN to STOP and when
the power supply is switched off.
When EZ is restarted in RUN mode, the timing relay continues
with the retentively stored actual value.
