The unit is suitable for rail mounting and wall mounting.
ELECTRICAL CONNECTIONS
Keep mains cables separate from signal and measuring cables. Twisted and
screened measuring cables are required (screen connected to earth).
Connected final elements must be equipped with protective circuits to manufacturer
specification. This avoids voltage peaks which can cause trouble to the transmitter.
The instrument must be protected by an individual or common fuse for a max. power
consumption of 10 VA per unit (standard fuse ratings, min. 1 A)!
aSignal and measurement circuits may carry max. 50 V r.m.s. against
ground, mains circuits may carry 250 V r.m.s. between the connectors.

EARTH TERMINAL (for grounding interferences)
If outside interference voltages act on the instrument, functional troubles may be
caused (concerns also high-frequency interferences). For grounding interferences
and ensuring the electromagnetic immunity, an earth must be connected: Terminal
22 must be connected to earth potential by means of a short cable (approx. 20 cm,
e.g. to cabinet ground)! Keep this cable separate from mains cables.

HINTS ON THE PARAMETER LEVEL
Filter time constant t_F
Adjust the filter time constant to the time, at which the signal variation is acceptable.
Filter bandwidth b_F
The bandwith is the adjustable tolerance in which the filter is active. Changes of the
process value larger than the adjusted bandwith are not filtered and will be transferred
directly to the output.
Example:Signal variations are e.g. +/- 1,5 mV. The filter bandwidth must be adjusted
directly to this variation.Enter: 1.5

EXAMPLE
1.) A container has a weight of 200kg (Fig. 4) , The max loading is 1000kg. The
resulting total weight is 1200kg. The load cells provide a signal of 1 mV/V and
are specified for 500kg. The MP 25 -transmitter provides a bridge supply of 12 V.
Thus we get 12 mV at 1500kg.
Span start is at 200kg --> the load cells deliver 1.6mV .
Span end is at 1200kg --> the load cells deliver 9.6mV.
The transmitter shall provide an output signal of 4...20 mA (2.. 10 V) .

TARE FUNCTION
Starting point for a tare function is the operating level:
+Prerequisite at configuration level 3 Corr =1rpage 9
TARE:
Watch display (container tare weight signal) and wait, until the measurement
value is stable.
Press key D5 during 5 seconds.
Subsequently, the following value is displayed : -0-
This operation can be repeated several times.
Deleting:
Press key Dduring approx. 15 seconds.(After 5 seconds, the tare value is
displayed: -0-.) Only after this tare display has stopped, the tare correction
was deleted and key D can be released.
gAfter changing the sensor, the decimal point or the measuring range (change in
Con1), another taring operation must be carried out, or the current one must be
deleted.
+After measurement value correction, the access should be disabled again.
Corr =0rpage 9
Another simple possibility for tare adjustment is by connecting terminals 2 and 3
shortly.
A blocking function for this can be realized by means of key switch.

MAINTENANCE / PROBLEMS / TROUBLE SHOOTING
The unit is maintenance-free. The hints to be followed in case of trouble are:
wCheck mains (voltage, frequency and correct connections),
wcheck, if all connections are correct,
wcheck the correct function of the sensors and final elements,
wcheck the configuration words for required functions and
wcheck the adjusted parameters for required operation.
Check any problems according to the table given below.
wIf no solution can be found, the transmitter must be shut down and replaced.
Problem Solution
Faulty measurement value Delete input signal correction, re-correct
Press key Dduring approx. 15 seconds.
“9999” is displayed
Required parameter not existing Check configuration.
Relay flickering Increase hysteresis ; Check installation (cable run) -
check effects caused by external devices
Sensor break, although sensor o.k. check if connection of terminal rows swapped.
Input signal correction is not possible . Sensor break
Repair sensor break resp. lead
Cleaning
Housing and front can be cleaned by means of a dry, lint-free cloth. No use of solvents
or cleansing agents!
