Hysteresis (Dead band): Hysteresis (Dead band) application is shown in the figure.
Direction:
All the figures here are shown considering the setting is direct (Normal). If the settings
are reversing (Fail Safe), the relays will behave exactly the opposite. However, it’s worth
mentioning that the relays will be in off (de-energized state on Power on / reset
condition). They will energize only after approximate 5 seconds. When alarm type none
is selected, ALRAM relay status depends on Direction.
Delay:
A time delay can be provided for the actual output. The relay will operate after the set
delay time.
Standby operation:
For alarm types, 9 to 14, the relay action happens only after the PV has crossed the SP
after power on.
