11.1 Fault tables
Two fault tables are displayed below. Table1 refers to faults with the DV
EC... Pro. The previous page is referenced twice her. This concerns the
testing of the pressure transmitter.
Table 2 refers to faults in a DV EC...
Pro unit with controller(s). You can examine the entire regulation circuit
using this table. Check the entire unit using the table. Follow the inst-
ructions from top to bottom. In this respect, only the instructions which
are checked off in the corresponding controller column shall apply. Then
proceed as follows:
Does not rotate Red All No 230 V~ between
‘L’ and motor ‘N’
No communication with
motor
- Defective cable to motor
or control system
Check cable or
replace control system
Does not rotate Red All 230 V~ between
‘L’ and motor ‘N’
No communication with
motor
- Defective cable to motor
or control system
Check cable or
replace control system
Does not rotate
Red All No 2.5 V between motor
RSA and motor RSB
No communication with
motor
- Defective cable to motor
or control system
Check cable or
replace control system
Does not rotate
Red All 2.5 V between motor RSA
and motor RSB
No communication with
motor
- Defective cable to motor
or control system
Check cable or
replace control system
Does not rotate
Red All No 10 V= or more at
release contact
None Speed: 0 U/min. Interruption in release
circuit
Check release circuit,
also between DV EC...
Pro and controllers, see
second table.
Does not rotate
Red All - Hall senor - Defective motor Check motor wiring,
replace motor
Does not rotate
Off All No 230 V~ between
‘L’ and motor ‘N’
No connection - No
supply voltage
Connection, check
operating switch and
electrical system
Does not rotate
Off All 230 V~ between
‘L’ and motor ‘N’
No connection - Defective control system Replace control system
Does not rotate Red All - Internal communication
error
- - Replace control system
Does not rotate Red All - Temperature control
system
- - Check free-running of
impeller
Rotates (too slow) Red All - Temp. motor Speed is lower than
desired speed
Motor runs with
difficulty
Check free-running of
impeller
Rotates (too slow)
and makes a lot of
noise
Red All - Temp. motor Speed is lower than
desired speed
Impeller does not rotate Check free-running of
impeller
Rotates constantly at
high speed
Green External controller 10 V = between
0-10 V and GND
None No specific features Impeller blocked Replace control system
Rotates constantly at
high speed
Green External controller If terminals
‘10 V’ and ‘0-10 V’
are connected
None - Wiring fault Correct wiring
Table 1:
- Ensure that the terminals ‘18 V’ and ‘GND’ of the sensor are supplied
with a voltage of 18 V = (from the control system or external).
- Measure the control signal at terminal ‘Sensor’ and ‘GND’.
Signal can be checked by pressing the hose together with two fingers
(voltage increases).
- Compare the pressured measured by the pressure sensor (the
‘Sensor’ value in the ‘Status’ menu), with the measurement result of
an ‘external’ pressure gauge. Use the same pressure hose.
