Maintenance - Weller KHE Betriebsanleitung

English--KHE
Thank you for placing your trust in our company by purchasing
the Weller KHE / KHE 81 Stop + Go Rest. Production was based
on stringent quality requirements which guarantee the perfect
operation of the device.
1. Caution!
Please read these Operating Instructions and the attached
Safety Information carefully prior to initial operation. Failure to
observe the safety regulations results in a risk to life and limb.
The manufacturer shall not be liable for damage resulting from
misuse of the machine or unauthorised alterations.
The Weller KHE / KHE 81 Stop + Go Rest corresponds to the EC
Declaration of Conformity in accordance with the basic safety
requirements of Directives 2004/108/EEC, 2006/95/EEC and
2011/65/EU /(RoHS).
2. Description KHE / KHE 81
The KHE / KHE 81 Stop + Go Rest is a switch-off and follow-up
control for the WFE soldering fume extraction device.
The soldering iron rest has a zero-voltage guide connection to
the control unit. In rest KHE 81, the light signal is transmitted to
the control unit by an LED. In the case of rest KHE, the light inlet
is located in the holder funnel.
The solder fume extractor cuts out approximately 20 sec.
after the soldering gun is placed in the holder.
3. Commissioning
Check that the mains voltage is consistent with the information
on the type plate. If the mains voltage is correct, plug the con-
trol unit into an earthed safety socket.The green LED (2) indica-
tes that the system is ready to operate. The control unit is
equipped for the operation of 2 soldering iron rests.

When being operated with one soldering iron rest only, the
second light guide inlet has to be kept sealed. To connect the
light guide (1) loosen the clamp nut and insert the light guide as
far as the stop, then screw up the nut finger-tight. Next, insert
the WFE mains cable into output socket (4) of the control unit
and switch on.
KHE:
Place the FE soldering iron in the soldering gun holder and make
sure that the light inlet (1) is completely covered by the soldering
gun.
KHE 81:
Insert the soldering gun plug into the socket in the safety rest.
Connect the safety rest connecting cable to the soldering station.
To ensure that the over-run control device functions properly, the
temperature of the soldering gun must be within the control
range.
The solder fume extractor WFE shuts down after approx. 20 sec.
The WFE restarts when the soldering gun is removed from the
soldering gun holder.
Standard setback (in digital soldering stations)
If the soldering tool is not used within a period of 20 minutes
the temperature will be automatically reduced to a standby
temperature of 150°C (300°F). After three setback periods
(60 min.) the "AUTO OFF" function will be activated and the
soldering iron will be switched off.

4. Maintenance

To ensure that the
it is important to ensure that the optical fibre (1) is connected
correctly between the holder and the control unit. If the optical
fibre is damaged, it can be cut to length again. In holders KHE,
the light inlet in the holder funnel must be cleaned with alcohol
(methylated spirit) at regular intervals.
If the light inlet of the optical fibre (1) is damaged, the optical fibre
can be reinserted and cut to length again.
For this purpose, the screw fitting of optical fibre (1) on the
soldering gun holder must be undone.
To replace the mains fuse, the control unit must be switched off
and isolated from the mains and the 4 control unit casing bolts
must be removed. The fuse holder for glass tube fuse (5x20) is
on the circuit board.
