Operation manual for BAUER RAINSTAR Series T32, T42 55
10.
Electric shut-
off valve
does not
close or
open
Program constant
1. The ECOSTAR is not programmed for a shut-off valve.
On the parameter sheet no.1.under program constant 6 appears
setting „2“.
The constant needs to be corrected to „0“ (with shut-off valve
overpressure)
Furthermore on the parameter sheet no.2 under machine „12“ the
following value must be entered:
Correct
adjustments
„1“ for both regulating motors (with shut-off valve)
Pressure switch
2. If a pressure switch for a shut-off when pressure is low is installed the
reasons could be the following:
a) Not enough pressure for operating, the pressure is below the value
which was adjusted at the pressure switch RAINSTAR.
Increase
pressure
b) Pressure switch dirty or defective.
In order to check the function of the pressure switch, the pressure
switch can be put out of operation in the program parameter sheet
no.2, constant 14, with adjustment „0”.
Dirt / Foreign bodies / Connections
3. The shut-off valve is mechanically blocked by foreign bodies.
4. The electronic connections of the shut-off valve are defective or not
correctly installed.

Turbine
regulation
does not
work, valve
remains
open or
closed
1. Limiting bolt for the adjustment of the regulating valve is not adjusted
correctly, valve is closed too much and cannot be opened by the
motor. (See adjusting table for turbines TVR 60, the adjustment
depends on the discharge flow)
2.
Electronic connections to the motor (Motor 1) are defective or not
correctly installed.
3. Motor for regulation valve (Motor 1) defective
4. Foreign bodies disturb the function of the regulation valve.

Machine
stops during
operation
1. If the machine is equipped with a pressure switch, the machine can
stop if the inlet pressure is too low.
If the operation of the machine should be continued, the function of
the pressure switch can be switched off.
2. If the required (set) retraction speed is too high and the machine can
not reach it, for a period of 20min, the machine switches off as well.
This function, however, can be switched off:
Machine data, parameter sheet no.1, constant 4 (monitoring of
correct speed)
Adjustment e.g „20“ monitoring switched on
Adjustment „0“ monitoring switched off
Increase

Further open
questions
If further problems with the display, accuracy or other functions should
occur the set data of the ECOSTAR according to the constants of
parameter sheet no.1 and the machine data of parameter sheet no.2
need to be checked. If necessary please contact our customer service.
