2 Introduction
HF Tapping Control Unit (HF = High Frequency)
When tapping on transfer lines, special purpose machines and machining centers, damage of the tap cannot al-
ways be prevented. Occasionally, the threads are not tapped to full depth or are missing at all. Such faults remain
often undetected until assembling of the parts. This causes high remachining costs and means sometimes even the
rejection of the component. In combination with the BILZ WFL, WFLK or WFLP Quick Change Tapping
Chucks and Adaptors with safety clutch, the HF unit controls the thread depth, identifies possible tap breakage
during tapping operation and prevents such malfunctions.

Red ”ALARM” indicator and ”REL2” contact:
As soon as the HF receiver has identified an alarm signal, the ”ALARM” indicator lights up and the ”REL2” con-
tact opens.
This situation will remain unchanged even after alarm signal ends, until the receiver will be reset by pushing
RESET button of its front panel or by opening the bridge between pins 8 and 10 of the multiple plug X1.
Recognition of faulty thread spindle in case of collision alarm:
All HF transmitters in the chucks of one multi-spindle tapping station can operate on the same frequency, i.e. on
the same channel. To recognize the spindle of the faulty thread, the chuck shanks are equipped with detector
rings. When the length compensation of a chuck gets compressed, the detector ring will be moved upwards and
thus identifies the spindle of the faulty thread. After correction, the detector ring is to be pushed back by hand
into zero position. Minimum compression length to get a signal response from the chucks is 1 mm (.04”).
Recognition of the spindle with battery monitoring alarm:
In case of alarm, all chucks are to be released first. If luminous diode ”B.-CHECK” continues lighting or flashing
(HFS 3100): A battery monitoring alarm has occurred. The individual chucks of the different spindles are to be
compressed now in succession. When compressing the chuck giving battery monitoring alarm, luminous diode
”B.-CHECK” will discontinue to give light. When compressing any other chuck, the luminous diode
”B:_CHECK” will continue to light up resp. to flash.
The chuck giving battery monitoring alarm can be identified much easier by using the HF receiver
”HFC 70”.
After recognition of the chuck having caused battery monitoring alarm and after battery replacement, the detector
rings are to be pushed back into zero position.
4.2.2 Standby operational mode
During intermissions (mains cut off) the receiver switches on periodically for short moments, to check if one of
the chucks is emitting battery monitoring alarm and, if any, memorizes it. During stand-by neither the indicator
diodes of the front panel nor the remote control relays are being activated. A fully loaded buffer battery
allows to maintain stand-by for abt. 3 weeks. After switching on again electricity supply system, the alarm indi-
cating diodes of the receiver’s front panel are being switched on, too, and the remote control relays are being
activated as well.
Recognition of the chuck having caused battery monitoring alarm, after switching on mains supply:
Weak battery Empty battery
• Red ”ALARM” indicator lights up.
• Yellow ”B.-CHECK” indicator lights up or
flashes in .5 sec. rhythm (HFS 3100).
• Red ”ALARM” indicator lights up.
• Yellow ”B.-CHECK” indicator does not light up.
see chapter 4.2.1 Check all chucks by compressing one after another.

5 The HF Receiver ”HFC 70”
The use of the HF receiver ”HFC 70” is of help to easily identify a chuck having caused battery monitoring
alarm.
Such chuck can be identified by making contact to the transmitting antenna (yellow ring) of the chuck by the
”HFC 70” antenna.
Operating elements of the hand-held receiver
• ON button:
Hand held receiver is switched on as long as ON button is being pushed.
• Indication of signal level (by LED):
The level of the signal received by the stub antenna is being shown by LED row. A distinct deflection will be
seen only after the antenna bar has nearly touched the antenna ring on the chuck.
• Battery check:
A red LED in the left corner of the LED row is determined to show operating readiness:
fully charged battery:
when pushing ON button: LED lights up for a short moment
weak battery:
when pushing ON button: LED doesn’t light up
The battery is of standard 9 V bloc type.

6 Installation
6.1 General Information
The HF receiver is protected against interference pulses. Normally adjacent electrical motors, transformers, con-
trols, radios etc. will not cause alarm signals. On the operating frequency, interference signals must not exceed
the maximum level of -93 dBm.
The field strength of the HF signal transmitted by the chucks stays below the permitted upper limit, and thus
interference with other radio services and other electronic equipment are prevented.
We recommend that BILZ HF Equipment on adjacent machines is operated on different channels to avoid
mutual interference.
6.2 Assembly
HF Quick Change Tapping Chucks
The insertion of HF Quick Change Tapping Chucks into the spindle is simple and follows the same principle as
standard chucks. However, avoid damaging the yellow isolation of the antenna ring which neither must be com-
pletely screened by metallic items.
Receiver antennae
2 (HFE 3002) or 4 (HFE 3004), respectively, antennae can be connected to the HF receivers. The positioning of
the antennae should be as close as possible to the chucks, however far enough away from metallic parts (mini-
mum distance 30 cm), to avoid weakening of the HF reception field.
The ideal length of the antenna bar is one quarter of the wavelength, as a rule the antenna is abt. 1.1 m long (HFA
0). However, if lack of space prevents the use of such antenna, a shorter one (HFA 2) can be used.
The antenna cable (RG58U) should be as short as possible; the maximum length between each antenna and the
receiver is 25 m. Please handle the antenna cable with care, do not pull nor bend it!
Level output on the front panel of HF receiver
To make installation easier and to evaluate the strength of a signal received, the receivers are equipped with a
level output which can be connected to standard voltmeters.
Digital voltmeters must not be used, as they cannot react quickly enough to the transmitter’s pulsed
signals.
To evaluate the level of a signal received by a certain antenna, only this one is to be connected to the re-
ceiver. All other antennae are to be disconnected from the receiver so far.
The voltage at the level output is increasing depending on the level of the signal received.
The following standard values should be considered for new transmitter batteries:
• Voltage < 1 V: weak signal received, improve antenna positioning.
• Voltage > 2 V: good signal received.
Additional Antennae
If, despite optimal antenna positioning, the signal level remains too low (metal parts and/or coolant may affect
transmission fields), additional antenna rings combined with rods can improve the radiation of signals from the
chuck group. These are special items to be designed for each individual case. For any further advice we will be
gladly at your disposal.

HF Tapping Control Unit
System HF 3000
Check-list of HF Tapping Control Unit, system HF 3000
for HF alarm.
The HF Tapping Control Unit supervises tapping during machining process and
indicates arisen faults by alarm signal.
The HF receiver differentiates
between: 1. Procedure alarm due to faults arisen during
tapping operation
2. Battery monitoring alarm due to battery voltage
fallen below limit value
Machine stop due to
procedure alarm
Red LED ALARM at the receiver lights
up, detector ring of the chuck displaced
Cause of malfunction:
Length compensation of chuck com-
pressed due to:
a. released safety clutch by:
− worn out tap
− wrong torque setting in
adaptor
− cored hole too narrow
− cored hole not deep enough
− lack of coolant
b. missing cored hole
c. cored hole not chamfered
d. insufficient initial cutting pressure
by the chuck
Machine stop due to
battery monitoring alarm
Red ARARM and yellow LED BATTERY ALARM
at the receiver light up, detector ring of the chuck
not displaced.
Cause of malfunction:
Battery voltage below limit value.
Such alarm may arise during machining process
as well as during non working time of the machine.
Recognition of the spindle having caused
battery monitoring alarm
The hand-held receiver HFC 70 helps to identify
the chuck having signalized the malfunction.
The chuck emitting alarm signal will be identified
by making contact to the chuck’s transmitting antenna
(yellow ring) by the „HFC 70“ antenna.

Recognition of the spindle having caused
procedure alarm:
Since at procedure alarm the length com-
pensation of the chuck is always being
compressed, the detector ring of the chuck
is inevitably being displaced, thus allowing
to identify the chuck having signalized mal-
function, even at multispindle operation.
After eliminating malfunction push back
detector ring into zero position and cancel
alarm signal by pushing reset button. Now
the machine is ready for operation again.
Malfunction signal is being indicated by
LED bar graph array.

LED bar graph array
Battery monitoring alarm may also be
recognized without the use of HFC 70:
The chucks are to be compressed in
succession. The chuck having signalized
battery monitoring alarm will be recognized
by the fact, that the yellow LED of the
receiver discontinues to give light as long as
the chuck is being compressed.
