the CAN--bus should be fitted with an termination
resistans. One of the CAN--bus end points is in the
programming box which has a built--in resistor. T he
other one is in the power source and should be fitted
with an termination resistans if the output in question is
not used. F or the location of the resistor, see the

6.2 Cooling unit
N.B. To give room for the cooling unit under the welding
power source, the tool box on the carriage must be
dismounted.
Screw the cooling unit and the welding power source
together.
6.3 Overheating protection
The LTS is provided with a thermal cut--out which trips in case of too high
temperature. The welding current is interrupted and an orange indicating lamp on the
front of the power source lights up. The programming box also shows an error
message. The thermal cut--out is reset automatically when the unit has cooled down.
6.4 Flow guard, water
If there is no cooling water flowing, the flow guard will block the welding power
source. The welding current is then interrupted and an error message is displayed in
the character window of the programming unit.
6.5 Flow guard, gas
The flow guard interrupts the ongoing welding process if the gas flow falls below 6
l/min. An error message is displayed by the programming box.
6.6 Error messages
The welding power source has a built--in function for handling error messages. All
error messages are presented in the programming box, and in some cases
measures will be taken automatically. See also programming manual 0457 706 xxx.

7 MAINTENANCE
Note:
All warranty undertakings given b y the supplier cease to apply if the customer
attempts to rectify any faults on the machine during the warranty period.
Only those persons who have appropriate electrical knowledge (authorised
personnel) may remove the safety plates to connect or carry out service,
maintenance or repair work on welding equipment.
7.1 Check--up and cleaning
Generally LTS 160 and LTS 250 does not require any
maintenance. Normally, it is sufficient to blow out the
machine using clean, compressed air (reduced pres-
sure) annually, and the dust filter should be cleaned
regularly. If the machine is set up in dusty or dirty
environment the machine and the dust filter should
be cleaned more often.
Dismounting the filter
8 ORDERING OF SPARE PARTS
LTS 160, L TS 250 is designed and tested in accordance with the EN 60974--1 (IEC
50199) international standard.
