Creating Self-Toggling (Pulsing) Relays Using
LogicsManager

Various functions are possible with the
LogicsManager
. This is a simple example of a relay output that toggles
from energized to de-energized in automatic mode with adjustable on and off time. This pulsing relay may be
combined with a flexible limit, which can be programmed with a function like low battery voltage to get a blink-
ing warning light.
Relay 2 is the discrete output (DO 2) and Flag 5 is used as an auxiliary flag. Relay 2 will be ON (energized) for 2
seconds and then OFF (de-energized) for 2 seconds as long as the easYgen is in automatic mode.

In this example is the Delay ON time in the
LogicsManager
of Flag 5 indicates how long the pause is. The Delay
OFF time of Relay 2 is the pulse duration.
