Timers
The VAMP protection platform includes four settable timers
that can be used in many different applications that require
actions based on time. Each timer has its own settings. The
selected on time and off time is set and then the activation of
the timer can be set to be as daily or different week days (See
the setting parameters for details). The timer outputs are
available for logic functions, block and output matrix.
Figure 2.10-1. Timer output sequence in different modes.
The user can force any timer, which is in use, on or off. The
forcing is done by writing a new status value. No forcing flag is
needed as in forcing i.e. the output relays.
The forced time is valid until the next forcing or until the next
reversing timed act from the timer itself.
The status of each timer is stored in non-volatile memory when
the auxiliary power is switched off. At start up, the status of
each timer is recovered.
