zone
01-00-**-IZ-011 –
Latch A
zone
**-**-**-TM-021 –
Latch B Timer
Latch B Timer is included in the equation so that Latch A will unlatch (become inactive) during
the second pulse (when Latch B Timer starts).
8. Create another monitor input zone. Tag this zone
Latch B
.
9. Select the zone, click the
Advanced Logic
tab, and then click
Edit
.
10. Create the following equation:
**-**-**-TM-020 EQU TIMER_EXPIRED AND (NOT 01-00-**-IZ-007 OR
01-00-**-IZ-012)
**-**-**-TM-020 –
Latch A Timer
01-00-**-IZ-007 –
Input Switch
zone
01-00-**-IZ-012 –
Latch B
zone
This equation becomes true when the switch is pressed for the second time or the input
becomes inactive. Latch B will remain latched until the switch becomes active or the input
becomes active.
11. Select
Latch A Timer
in the
Custom Timers
section on the left side of the Configurator
window.
12. Click
Edit
under
Advanced Logic
.
13. Add the
Latch A
zone to the equation.
When the Latch A zone becomes active, this timer will start.
14. Select
Latch B Timer
.
15. Click
Edit
under
Advanced Logic
.
16. Add the
Latch B
zone to the equation.
When the Latch B zone becomes active, this timer will start.
17. Select the output relay, click the
Advanced Logic
tab, and then click
Edit
.
18. Create an equation that will be true if either Latch A Timer or Latch B Timer is running:
**-**-**-TM-020 EQU TIMER_RUNNING OR **-**-**-TM-021 EQU TIMER_RUNNING
**-**-**-TM-020 –
Latch A Timer
**-**-**-TM-021 –
Latch B Timer
You have successfully created a relay pulsing sequence.
Attention: We recommend that you do not apply an equation directly to an output,
except in special cases.
