Figure 458:
Travel time calculation when Travel time Clc mode is “From Cmd to Pos”
There is a time difference t
1
between the start of the main contact opening and the
OPEN_CB_EXE command. Similarly, there is a time gap t
2
between the time when the
POSOPEN
auxiliary contact opens and the main contact is completely open. Therefore, to
incorporate the times t
1
and t
2
, a correction factor needs to be added with t
open
to get the
actual opening time. This factor is added with the
Opening time Cor
(= t
2
- t
1
) setting. The
closing time is calculated by adding the value set with the
Closing time Cor
(t
4
- t
3
) setting
to the measured closing time.
The last measured opening travel time
T_TRV_OP
and the closing travel time
T_TRV_CL
are available in the monitored data view on the LHMI or through tools via
communications.
Alarm limit check
When the measured opening travel time is longer than the value set with the
Open alarm
time
setting, the
TRV_T_OP_ALM
output is activated. Respectively, when the measured
closing travel time is longer than the value set with the
Close alarm time
setting, the
TRV_T_CL_ALM
output is activated.
It is also possible to block the
TRV_T_CL_ALM
and
TRV_T_OP_ALM
alarm signals by
activating the
BLOCK
input.
