Transmitter Multiparameter M400 47

Printed in Switzerland 52 121 378

The sensor keeps the information stored in the built in electronics and can be retrieved via a

transmitter or the ISense asset management suite.

The alarm will be reseted if the Lifetime Indicator is not 0 days anymore (e.g. after connecting a

new sensor or changes on the measurement conditions).

For amperometric Oxygen sensors, the lifetime indicator is related to the inner-body of the

sensor. After exchanging the inner-body, reset the lifetime indicator in the ISM Setup menu (menu

Conﬁgure).

For optical DO sensors the lifetime indicator is related to the OptoCap. After exchanging the

OptoCap, reset the lifetime indicator in the ISM Setup menu (menu Conﬁgure).

If the Lifetime Indicator is turned on, the value will be automatically shown in the display on line 3.

Adaptive Cal Timer: This timer estimates when the next calibration should be performed to keep

the best possible measurement performance. The timer is inﬂuenced by signiﬁcant changes on

the DLI parameters.

Adaptive Cal Timer YES / NO

Alarm YES / NO R# choose relay

The alarm will be reseted after a successful calibration.

If the Adaptive Cal Timer is turned on, the value will be automatically shown in the display on

line 4.

NOTE: The recommended initial value for the calibration interval will be uploaded from the

sensor to the transmitter and can be adapted according to the application experience (menu

Conﬁgure / ISM Setup / Sensor monitoring).

Time to Maintenance (not for optical sensors): This timer estimates when the next cleaning

cycle should be performed to keep the best possible measurement performance. The timer is

inﬂuenced by signiﬁcant changes on the DLI parameters.

Time to Maintenance YES / NO

Alarm YES / NO R# choose relay

The alarm needs to be reseted in the menu ”ISM Setup”. For oxygen sensors, the time to

maintenance indicates a maintenance cycle for the membrane and electrolyte.

NOTE: The recommended initial value for the maintenance interval will be uploaded from the

sensor to the transmitter and can be adapted according to the application experience (menu

Conﬁgure / ISM Setup / Sensor monitoring).

8.6.2 CIP Cycle Limit

Please activate the function ISM (see chapter 8.2.1) conﬁguring the CIP cycle limit.

The CIP cycle limit counts the number of CIP cycles if the limit (user deﬁned) is reached, an

alarm can be indicated and set to a certain output relays. The following options are possible:

CIP Max 000

Alarm YES / NO R# choose relay

If the Max setting is on 000, the counter functionality is turned off. The alarm will be reseted after

exchanging the sensor. For oxygen sensors, the counter can be reseted in the ISM Setup menu
