A.1
Abbreviations, Terms
2.WLD
2nd Weld time: main weld time, can consist of a block comprising individual impulses, only
the 2.WLD can have upslope and downslope
BDT
Block delay time, time between block start and first %I impulse
CT
COOL
Cool time: time between the current pulses/blocks (1., 2., 3. COOL (CT))
Current
Current measured in %I (scale units) or kA (same as HEAT).
DST
Down Slope Time: until the end of 2. WT current is reduced gradually.
EA (EO)
Electronic output: in this case +24V through transistor
EOS
End-of-Sequence contact: signal is output when the spot has been completed
Ext
External, e.g. +24V: voltages for signal transmitters (switches) and actuators (valves)
external to the timer
Firing
(Ignition)
Weld on/Weld off: enabling and disabling of the firing (ignition) impulses for activating the
power unit.
HEAT
Heat in %Ht or kA (same as current)
HLD
HOLD
Hold time: last time of the welding schedule; time following the last weld time, during which
the parts just welded are allowed to cool down
HSA
Main switch trip
IMP
Number of pulses forming the 2.WLD
LT
Power Unit (thyristor or inverter)
NBS
Mains load limitation control: for monitoring and influencing the mains load
OFF
Off time: time between 2 spot welds during which the solenoid valve is not activated. Avail-
able only in REPEAT mode.
PG
Programming unit/welding computer
Post-
Heating
Time
Also called 3. WLD.
Pressure
(Monitor)
Contact
(MC)
Monitor Contact: e.g. monitoring of the pressure in the cylinder that closes the electrodes, or
monitoring of the electrode position; gun closed.
PSG
Transformer rectifier unit for the PSU inverter
PSI
Inverter power unit (1000 Hz)
PSL
PS power unit
PSP
PS programming module
PSS
PS timer
PST
Thyristor power unit (50/60 Hz)
PSU
Weld current inverter (medium frequency)
RA (RO)
Relay output, +24V are output via a contact
REPEAT
Repeat mode: for manually operated systems only
