1. General information
The HC960 chipper controller includes automatic control for the feed rollers of a wood chipper, a revolu-
tion counter, a daily counter and a total operating hours counter. When operating the HC960, a distinction
is made between two different operating states.
1.1. Operating states
Normal operation
In normal operation the HC960 has a display function. Depending on whether the blade shaft is rotating
or not, either the speed or the total operating hours are displayed.
Before the HC960 can be used, a basic parameter setting must be made. On the following page the indi-
vidual parameters are listed both with their designation (these appear in the display) and their meaning.
Programming the parameters
Setting different basic values to adapt the HC960 to different chipper types. Programming the parameters
is only necessary during initial commissioning.
1.2. HC960 operating modes
When operating the HC960, a distinction is made between fully automatic (Normal RPM parameter > 0)
and semi-automatic mode (Normal RPM parameter = 0). The user can decide for himself in which operat-
ing mode he wants to operate the HC960.
In semi-automatic mode, the blade shaft must be raised to the desired speed after starting the diesel en-
gine. This target speed can then be saved by pressing the set button. The feeder is switched on at the
same time. The set display flashes until the target speed is set for the first time. If the speed of the blade
shaft is changed during operation and then the set button is pressed again, the new target speed is
saved. This happens every time the Set button is pressed.
2. Meaning of parameters
Name Meaning Remark
Normal
RPM
Normal speed Preset target speed which the blade shaft should hold and at which
the feed rollers are started (if a restart speed is programmed, this has
priority; see also Return RPM parameter). After a drop in speed, the
target speed must be reached again in order to switch on the feed roll-
ers again. If the value "0000" is entered here, this means that the
blade shaft must be brought to a certain speed after starting the motor,
which can then be saved by pressing a button (learn function).
Permitted value: 0 - 5000 rpm
The limits are influenced by the settings for overspeed and under-
speed
Return
RPM
Restart speed Speed at which the feed is switched on again. (Note: this parameter
has priority over the parameter "n"). It is only to be used in semi-auto-
matic mode. A value should be entered here which is slightly below
the normal speed. As the value for the normal speed in this operating
mode can be changed at any time via the learn function, it is recom-
mended to enter a percentage value. In fully automatic mode the value
"0" must be entered here. The entry can be a percentage or an abso-
lute value, depending on the procedure for entering the minimum
speed.
Permitted value: 0 - 99% or 0 - 5000 rpm
The limits are influenced by the settings for overspeed and under-
speed

LOW
RPM
Underspeed Deviation from the target speed. If the speed falls below this minimum
speed, the feeder is stopped to allow the blade shaft to reach its target
speed again. The minimum speed can be entered both as an absolute
value and as a percentage deviation from the target speed. To enter a
percentage deviation, use the minus button (down arrow) to go past
zero. A percentage value is indicated in the display by a "%". For ex-
ample, "5%" corresponds to a percentage deviation of 5%. If the dis-
play shows "0850", for example, this means that 850 rpm has been
programmed as the minimum speed. If a "zero" is entered for this pa-
rameter, the minimum speed is not monitored.
Permitted value: 0 - 99 % or 0 - 5000 rpm
Over
RPM
Overspeed Upper permissible speed of the blade shaft. If this speed is reached or
exceeded, the feed rollers are stopped. The entry can be a percentage
or an absolute value, depending on the procedure for entering the
minimum speed. If a "0" is entered for this parameter, the overspeed is
not monitored.
Permitted value: 0 - 99% or 0 - 2700 rpm

rotation
Number of pulses emitted by an initiator per revolution of the blade
shaft.

4. Programming the parameters
The parameters must always be programmed when the machine is at standstill. To access the parameter
setting in operating mode, switch on the device while holding down the set button. Press the set button
until the display shows "*** parameter ***". Use ↙and ↗to scroll to the desired parameter. Use "set" to
be able to change the parameter. Afterwards the value can be adjusted with ↙and ↗ and saved with
"set".
Termination of programming
If programming is terminated by switching off the device, all changes made since the last time the set but-
ton was pressed are retained.

7. Operating hours counter
The HC960 has two independent operating hours counters: A resettable daily operating hours counter,
which can be used for maintenance intervals, for example, and a settable total operating hours counter.
While the blade shaft rotates, its speed is automatically displayed. If you wish to display the daily operat-
ing hours instead, briefly press the set button once in fully automatic mode (Normal RPM greater than
zero). In semi-automatic mode (Normal RPM equals zero), however, the set button must be pressed for
longer than 3 seconds, as in this operating mode a brief keystroke will cause a new target speed to be
adopted.
To clear the daily operating hours counter, press the set button for longer than 3 seconds in both operat-
ing modes. After these 3 seconds have elapsed, there is a switchover to the display of the daily operating
hours. After a further 3 seconds (the set button is still pressed), the daily operating hours counter is
cleared. “0:00" appears. The specified times apply in each case starting from the speed display.
If no button is pressed for ten seconds, there is an automatic switchover back to the speed display.
When the blade shaft is stationary, the total operating hours (th = total hours) automatically appear in the
display. Here too, briefly pressing the set button switches to the display of daily operating hours.
The procedure described above for resetting the daily operating hours counter also applies here. If no
button is pressed for ten seconds, the display automatically switches to the total operating hours.
The total operating hours counter can be set via the parameter menu.
8. Output assignment
Depending on whether you need a N.O. or a N.C. contact for your magnet of the feed control, select the
appropriate contact on the HC960. Please also note the function of the output states, which are described
in detail in Figure 1 on page 4.
