4.7.3 Relay outputs:
2 relay outputs
• Hysteresis independently programmable in the display unit
• Time delay independently programmable from 0 to 25 s, in 0.1s increases.
•
NO contact: 5 A - 250 VAC on resistive load
Activation or de-activating of alarm x
The state of relay x depends on the entered programming.
The relay x remains still.

Choice of the state of the relay associated led
The led indicates the alarm state.
Led lit when relay active (coil supplied)
Led still when relay active (coil supplied)
Setting of the hysteresis in display points if mode indicator
(SCALE YES). The hysteresis is active on switching from lit led
to still led, that is to say on switching out of alarm, as the led represents
the alarm state.
If the mode indicator (SCALE YES) is selected, the setting of the set-
points is in display points.
If mode transmitter (SCALE NO) is selected, the setting of the setpoints
is in input scale points.

• Time delay on the alarm
The relay time delay can be adjusted from 000.0 to 025.0s, in
0.1s. increases. It is active both on switching and switching back.
