In addition to these instructions, you must study and understand the applicable safety
information for the relevant base machine as well as any other equipment involved.
The user manual is supplied with supplementary documentation providing more detailed
descriptions of the installation, fitting, operation and maintenance of control systems and
custom modifications for your specific product.
Information, images, illustrations and specifications used in the instructions are based
on product information that was available at the time of going to press. Images and
illustrations used in the instructions are typical examples and not intended to be exact

handling, storage and processing. To prevent contamination of soil and water, spillages
must be avoided. Should a spillage occur, it must be dealt with.
Hazardous waste may only be disposed of by those authorized to do so. All waste
produced must be disposed of in compliance with applicable legislation and ordinances:
- Metal and plastics to be recycled.
- Hydraulic hoses are normally used for energy recovery (sort as hazardous waste).
- Oils and greases are normally used for energy recovery (sort as hazardous waste).
- Electronic components to be recycled for materials (sort as hazardous waste).

3 Operation
3. Operation
Make sure you have read and understood the entire chapter entitled Operation before
beginning the programming sequence.
The constant flow function in DC2 enables certain selected functions to run without
actively operating DC2 controls. When the constant flow function is installed according
to 9000224 Installation Instructions, selected functions can be activated to run without
operating the controls; all that is required is activation of constant flow. Activation/
deactivation of constant flow can be summarized as follows:
1. Programming sequence – specific functions and the specific flows they will have when
constant flow is activated are determined in the programming sequence.
2. Activation sequence – the activation sequence starts constant flow to selected
functions.
3. Deactivation – when constant flow is deactivated, all active functions that were started
in the activation sequence are stopped.
WARNING
If you have any doubts concerning the safety aspects
of your knowledge, the equipment or work, contact
a dealer or engcon Nordic AB. Incorrect installation
affect safety.
WARNING
Beware of moving parts. A lack of awareness may lead
to crush injuries. Risk of personal injury.
WARNING
Never attempt to increase the maximum capacity
of the equipment by modifications not approved by
the supplier. Risk of personal injury and damage to
property.
CAUTION
If constant flow is activated without activating a
function, the tiltrotator or tool may start unexpectedly
without any controls having been moved.

3 Operation
IMPORTANT
Maintenance and repair of the electrical system may only be
carried out by professionally qualified persons.

3 Operation
3.1. Programming sequence
1. Operate the desired function(s) using rollers or buttons: Extra1, Extra2, PWM5 or
PWM6. (Refer to the decal in engcon's user manual.) Example illustrated below when a
function is programmed to a roller and button:
EXTRA 2
2146492
2. Press the constant flow button; after 3 seconds a buzzer will sound in the DC2 cabin
module. Release the function roller/button:
- Speed and direction are locked for the constant flow functions in operation.
- The constant flow functions' speed and direction are saved.
WARNING
Beware of moving parts. A lack of awareness may lead
to crush injuries. Risk of personal injury.

3 Operation
3.2. Activation sequence
Can be operated immediately after the programming sequence without releasing the
button.
1. Hold down the constant flow button; selected functions are activated with the
programmed speed and direction.
2147270
2. After 3 seconds a buzzer will sound in the DC2 cabin module. If the operator releases
the button within 2 seconds after the audible signal (buzzer in the DC2 cabin module will
sound during these 2 seconds):
- The constant flow functions are activated.
- The audible signal is activated.
10

3 Operation
Check that constant flow is functioning (e.g. that the rotating brush is rotating).
Check that the indicator lamp is on.

place in the cab
IMPORTANT
If the button is not released within 2 seconds, the constant flow
function will start and the activation sequence must then be
restarted.
WARNING
Beware of moving parts. A lack of awareness may lead
to crush injuries. Risk of personal injury.
CAUTION
If constant flow is activated without activating a
function, the tiltrotator or tool may start unexpectedly
without any controls having been moved.
3.3. Deactivation of constant flow
Constant flow is deactivated for all activated functions should any of the below occur:
- Any of the constant flow functions is activated manually by a button or roller (e.g. if
Extra1 on the roller is moved, constant flow is deactivated).
11

3 Operation
- The constant flow button is depressed.
- The safety gate is opened.
- Faulty constant flow button.

4 Troubleshooting
4. Troubleshooting
Description of fault
Possible cause(s)
Suggested action
The alarm ”CONST FLOW
BLOCKED BY SAFETY GATE”
will be shown in the cabin module
display and in Microconf when a
constant flow button is depressed.
1. Safety lock lever signal not
connected.
2. Safety lock lever signal
incorrectly connected/
incorrectly configured.
3. Safety gate open.
4. Safety gate closed at system
start.
1. Check that the safety lock
lever signal is installed.
2. Check that the safety lock
lever signal is correctly
connected and correctly
configured.
3. Close the safety gate.
4. Open and close the safety
gate.
After a 2-second audible signal
from the DC2 cabin module,
the selected function will stop
working.
Activation interval exceeded.
During the activation system,
the constant flow button must be
released within 2 seconds.
Nothing happens when a constant
flow button is held down for 3
seconds or more.
Constant flow incorrectly
configured.
Check the constant flow installation
and configuration according to
9000224 Installation Instructions.
When the program sequence
is complete and the activation
sequence is performed, nothing
happens on the programmed
function.
The programmed function is not
activated for constant flow.
Check that the constant flow
configuration on the selected
function is activated for constant
flow activation.
The alarm ”CONST FLOW
BLOCKED BY PARAMETER
ERROR” will be shown in the
cabin module display and in
Microconf.
Incorrect parameter entry in the
cabin module.
