8.6 Activation delay tank monitor [H90]
The activation delay of the tank monitor is required to test the operation modes dur-
ing the commissioning without activating false alarms.
Activation
Delay is activated by the start of the tank monitor and suppresses all errors from F1
to F38 for a pre-set time (with the exception of F30).
After expiration of the set time the tank monitor is set to the basic condition and then
activated.
Premature stop of the activation delay
The activation delay can be finished by pressing the reset button twice quickly.
8.7 Sensor correction procedure
Sensor correction means:
A correction is applied to the value measured by the sensor. This is then cumulatively
effective over the whole measurement range.
An adjustment to the sensor correction is only necessary:
- in conjunction with first installation,
- if the sensor cable length is altered,
- when replacing a faulty sensor.
In order to adjust the sensor correction a reference thermometer is needed.
Proceed as follows:
Switch off power supply
Install / change sensor
Use the reference thermometer to establish the milk temperature.
Switch on control unit and set [c90] to the measured number of degrees.
The control unit calculates the difference between the reference thermometer
reading and temperature sensor 1 and automatically sets this in parameter [c91].
Parameter [c91] can be displayed and adjusted at any time.
Hold down the up and down arrow buttons simultaneously:
The settings are stored.
Proceed with the setting for sensor 2 (if present) in the same way. In this case pa-
rameters [c92 and c93] must be set.
