Error messages

Nine different error messages can be shown on the
display:
• NOTE! LOW VOLTAGE (1A) CHECK THE VOLTAGE
SUPPLY AND THE CABLE TO THE HYDRAULIC
UNIT
• LOW VOLTAGE PHASE X (1B) LOW POWER 32A
• MOTOR PROTECTION TRIPPED (2)
• MOTOR OVERHEATED (3) COOLING IN
PROGRESS. DO NOT SWITCH OFF THE ELECTRIC
MOTOR
• OIL TEMP. HIGH (4) CHECK THE WATER TO THE
HYDRAULIC UNIT
• PRESSURE SENSOR OUT OF (5) ORDER
• HIGH HYDR PRESSURE (6) CHECK UNIT
• NO CONTACT CHECK THE CAN CABLE (7)
• NO RADIO CONTACT (8)
Error message (1A)
CAUTION!
Low voltage Check the voltage supply and the
cable to the hydraulic unit
Too low voltage, caused by:
• Long mains cable.
• Too small core size (cross-section) on the mains cable.
One or more phases down, caused by:
• A fuse has blown in the distribution box.
• Cable breakage.
• No voltage to one or more phases in the distribution
box.
Action (1A)
Press OK to acknowledge the error message. The
hydraulic unit will match the maximum power output to 32
A.
Work procedure for wall sawing
Error message (1B)
"Low voltage Phase x low output. 32 A", where x
represents phase 1, 2 or 3.
Action (1B)
Press OK to acknowledge the message. It states on the
display that the maximum power output is set to 32 A. If
the voltage is still low, the electric motor is turned off and
the low voltage error message is shown.
By pressing OK, the unit returns to the maximum power
you selected at start up. To switch between 63 A and 32
A, the unit must be turned off and then on again.
Read the supply voltage on the operations menu "Phase
1, Phase 2, Phase 3". If the voltage, before the motor is
started, is:
Below 340 V, check that none of the cores in the cable are
broken and that there is voltage up to distribution box.
Above 340 V, check the cable's core dimensions and
length.
Error message (2)
"Motor protection tripped".
Cause (2):
The electric motor has been overload or a phase is down.
This is why the motor cut-out, which is there to protect the
electric motor, has tripped.
Action (2):
Press OK to acknowledge the error message. Check that
there is voltage to the hydraulic unit on all three phases.
Read the supply voltage on the operations menu "Phase
1, Phase 2, Phase 3".
If the voltage to one phase is down: Check the mains
cable and the voltage to the distribution box. The motor
protection is reset automatically within three minutes.
If the voltage to all phases is higher than 340V: Wait for
the motor cut-out to reset. Now restart the hydraulic unit.
If the motor cut-out trips frequently you should call the
service personnel.
Error message (3)
"Motor overheated cooling in progress. Do not turn off the
electric motor!"
NOTE!
Do not turn off the motor, as this can damaged
it. When the motor has cooled it is turned off
automatically.
