7. TIMER APPLICATION EXAMPLES
This section illustrates two common applications for
the BA377E-SS when configured as a Timer.
7.1 Measuring the time that a contact is
closed.
In this example a BA377E-SS is required to display
the time that a hazardous area contact is closed.
The display is required in hours and minutes within
the hazardous area and is to be reset to zero by a
push button located in the same hazardous area, not
by the instrument front panel push buttons. The
operator is required to zero the grand total by
operating the

No security codes are required to protect access to
the configuration menu or to the grand total reset.
When power is restored after a supply interruption
the Timer is to resume normal operation without
manual intervention.
Figure 18 shows the wiring for the BA377E-SS when
powered by a single channel Zener barrier.
