3.2 Glossary
Terms Description
t
start-up
Start-up delay
Once the supply voltage is applied, the start-up delay
t
start-up
begins. Measured voltage and frequency val-
ues changing during this time do not influence the
switching state of the alarm relays K1 and K2. At that
moment, the switching state of the alarm relays K1
and K2 depends on the "Start alarm" parameter
(menu: 3.8.4. Start alarm).
t
on
Switch-on delay
All switch-on conditions have to be met for the dura-
tion of the switch-on delay
t
on
so that the correspond-
ing alarm relay operates.
t
off
Response delay
Minimum period that a limit value infringement must
exist so that the corresponding alarm relay trips.
t
(off ) total
When the contact monitoring for switches/discon-
nectors is activated , the time until the switch/discon-
nector actually switches off ( t
(off) total
) is additionally
measured during a test.
The longer one of the two switch-off times is indicated
at
t
(off) total
(menu 1.15, see page 42).
