Relay Pulsing
TIMER_EXPIRED)
01-00-**-IZ-007 – Input Switch 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.
