Robot 185 Troubleshooting
The Oil Level indicator light is green, when the level of the hydraulic oil is within the approved limits. It
blinks red, when the level alarm is activated and continues blinking until the alarm has been acknowledged
with the acknowledgement button
(Ack) of the remote control. After the acknowledgement, the indicator
light is red until the fault has been corrected.
The
Service indicator light is green, when there is no need for anything other than the daily service.
It blinks red, when the service required alarm is activated and continues blinking until the alarm
has been acknowledged with the acknowledgement button
(Ack)
of the remote control. After the
acknowledgement, the indicator light is red, until there is no service need anymore. The indicator light
expresses, that the service interval has been met and that the replacement/cleaning of the rotary connection
is necessary.
The
Volt indicator light is green, when there are no problems with the power supply of the device. It blinks
red, when an alarm is activated and continues blinking until the alarm has been acknowledged with the
acknowledgement button
(Ack) of the remote control. After the acknowledgement, the indicator light is
red until the fault has been corrected. The indicator light expresses the over heating of the contactor and a
missing phase/a blown fuse in the 400 V operating voltage of the device.
Troubleshooting the electric system
The most typical fault in the electric system is that the machine has been connected to the wrong type of
power source.
Check the fuses of the electrical network and the machine. A blown fuse must always be interpreted as a
symptom of a fault. Find out what has caused the fuse to blow and fix the fault.
Check the cables and their fastenings (see Service/ “Electric”).
Remember to ensure that the machine is supplied with a supply voltage and that the voltage is stable and
large enough.
The fault can also be found in the switchboard, to which the machine is connected.
Troubleshooting the hydraulic system
Measure the circulation pumping pressure of the hydraulic system and the maximum pressure of the
machine (see Service/ “Determining hydraulic pressure”)
Also measure the feed pressure. It should automatically be 35 bars.
Adjust the maximum pressure to the correct level, if it is not correct. If the pressure in all the functions is
too low, there is a fault in the maximum pressure settings.
Note! Too high a setting in the maximum pressure of the pump may jeopardise the functionality
of the machine and break the hydraulic system.
If the pressure is correct, an electrical fault is possible. In this case, check the remote control and indicator
lights.
Listen to the sound of the machine. If the drain valve is open it is possible to hear it. The machine becomes
powerless and it cannot stand on the outriggers or lift anything.
With a hydraulic fault, the problem may be caused by a fault in the clapper valve or a leakage in the cylinder.
