REFER TO
FUNCTION
A
NA
No applicable = option.
B
JMB operational
Indicates green as the engine is working, with status everything ok.
C
Oil pressure (or dry run water tank or tem-
perature to high at pump inlet)
Indicates red as the key switch is put on, and it extinguish when the
motor is working. When the oil pressure is to low during operation, the
indicator lights on and the diesel engine will turn off, the alarm lamp will
NOT flash on the operating panel. It is therefore possible that this icon
is lit when there are other faults active (temperature inlet pump too high
and dry run of water tank). These disturbances will flash on the control
panel via the alarm lamp (see 4.2 -. Paragraph 11).
D
Water temperature
Indicates red as the key switch is put on. The system is carrying out a
control and the indicator extinguish if the water temperature is good. If
the water temperature of the diesel engine is to high, this indicator will
light on and the engine will turn off.
E
Dynamo
Indicates red as the key switch is put on and extinguish when the dy-
namo delivers tension. When the dynamo delivers no tension while the
diesel engine is running, this indicator will light on.
F
NA
Indicates red as the key switch is put on. The system is carrying out a
control and the indicator extinguish.
G
Engine preheat
Indicates orange if the key switch is put on, and extinguish when the
diesel engine is preheated.
H
Vacuum air filter
Indicates red as the key switch is put on. The system is carrying out a
control and the indicator extinguish if the filter passage is good.
When the air filter is polluted, the indicator will light on continues until
the filter is cleaned or replaced and the contact is reset.
I
NA
This indicator is not in use.
J
Hours counter
Here one can see the actual working hours of the machine.
4.6. Pumps HT
There must be present a pre - pressure (pump) at HT pumps (pumps with high temperature).
The pre - pressure (pump) must provide for sufficient flow of water to feed the high pressure pump and to occur
cavitation. Cavitation is the phenomenon that in a moving fluid the local pressure is going to be lower than the
vapour pressure of the fluid. Because of this mist bells will arise who can implode with high power in the pump
and could cause damages. For all these applications at high temperature, it is ABSOLUTELY ESSENTIAL to feed
the pump with positive pressure (at least 3 bar) and with a sufficient quantity of water.
4.7. Scope of application
Efficient high pressure cleaning is achieved by following a few guidelines combined with your own experiences.
Each cleaning job is different and specific, therefore contact DiBO for the best solution in your application sector.
Using cleaning products (if applicable): the surface to clean should be sprayed so the product can act during
some time (do not let it dry!) before cleaning with high pressure jet.
Cleaning agents can increase the cleaning effect if they are used correctly!
Always follow/consider the safety instructions of the used product!
Cold water (high pressure) cleaning: removal of (mild) impurities/pollution and rinsing.
Hot water (high pressure) cleaning (if applicable): the cleaning effect will be such improved through increasing the
temperature (set the temperature experimentally according to the application).
Cleaning via lance with rotating head (if applicable): cleaning method to remove tough layers of dirt.
Cleaning using a steam lance (if applicable): this steam function (by overheating water) is used in ‘sensitive’ clean-
ing applications (eg: damage sensitive surfaces) where there is stubborn dirt (eg: degreaser) is removed by using
steam.
Please note: this application has high cleaning temperatures and requires various safety measures!
