Enter the desired value(s) for the Setpoint and press [ENTER]

This screen provides the option to conﬁgure a setpoint to be active on an over range condition.

Select the setpoint (1 thru 4) and ‘Yes’ or ‘No’. Select the desired relay that will activate when the

setpoint alarm condition is reached.

Over Range

Conﬁgure whether an over range should also be alarmed and which relay should be used. Once

conﬁgured, the selected relay will be activated if a sensor over-range condition is detected on the

assigned input channel.

Delay

Enter the delay time in seconds. A time delay requires the setpoint to be exceeded continuously

for the speciﬁed length of time before activating the relay. If the condition disappears before the

delay period is over, the relay will not be activated.

Hysteresis

Enter the hysteresis as a percentage-value. A hysteresis value requires the measurement to

return within the setpoint value by a speciﬁed percentage before the relay is deactivated.

For a high setpoint, the measurement must decrease more than the indicated percentage below

the setpoint value before the relay is deactivated. With a low setpoint, the measurement must

rise at least this percentage above the set-point value before the relay is deactivated. For exam-

ple, with a high setpoint of 100, when this value is exceeded, the measurement must fall below

90 before the relay is deactivated.

State

Relay contacts are in normal state until the associated setpoint is exceeded, then the relay is

activated and the contact states change.

Select ‘Inverted’ to reverse 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 the setpoint is

exceeded). ‘Inverted’ relay operation is functional when power is applied to the M300 trans-

mitter.

Pressing the [ENTER] key again will bring up the Save Changes dialog Selecting No will dis-

card the entered values and return to the measurement display screen, selecting Yes will save

changes made.
