Each Alarm Relay can be configured in either a Normal or Inverted state. Select ”Inverted” to re-
verse the normal operating state of the relay (i.e. Normally open contacts are in a closed state,
and normally closed contacts are in an open state, until an alarm occurs). ”Inverted” relay oper-
ation is functional when power is applied to the M300 transmitter.
In addition, a Delay for the activation can be set. Enter the delay time in seconds. A time delay
requires the alarm to occur continuously for the specified length of time before activating the re-
lay. If the alarm disappears before the delay period is over, the relay will not be activated.
If power failure is turned on, only inverted state is possible and cannot be changed.
Pressing the [ENTER] key again will bring up the Save Changes dialog. Selecting No will
discard the entered values, selecting Yes will make the entered values the current ones.
h
Please note, that there are additional alarms, which will be indicated in the display. See there-
fore in chapter 14 ”Troubleshooting” the different warning- and alarm lists.

cycle off. The cleaning time can be 0 to 9999 seconds and must be smaller than the Cleaning
Interval.
Select the desired Relay state: Normal or Inverted.
Pressing the [ENTER] key again will bring up the Save Changes dialog. Selecting No will
discard the entered values and return to the measurement display screen, selecting Yes will
save changes made.
