&217$&7257(03(5$785(/,0,76:,7&+: If the Temperature Limit Switch is
activated (open), the control cannot be initiated. The initiation will remain inactive until the
Temperature Limit Switch cools (resets). If the Temperature Limit Switch is activated
(opened) during WELD Time, the firing pulses to the contactor will continue until the end
of WELD Time. Then, HOLD and OFF time will follow. A new sequence cannot be
initiated as above, until the Temperature Limit Switch cools and resets. The DATA Display
will display an ERROR Code 01 in DATA Display (4) until the Temperature Limit Switch
recovers its normally closed state. At this time, the DATA Display will again display the
data stored in the currently selected Function. See TROUBLE SHOOTING section 13.1.
If during CONTINUOUS or INTERMITTENT SEAM WELDING, the Temperature Limit
Switch is activated, it is the same as opening the initiation. If the Temperature Limit Switch
is opened, the Weld Schedule will end. A flashing ERROR Code 01 will appear in the
DATA Display (4) when the Temperature Limit Switch opens.
Depending upon machine requirements a flow switch can either be substituted for a
Temperature Limit Switch or wired in series with the Temperature Limit Switch. The
operation as described above will still be similar.
NOTE: This feature is a programmable feature and is factory programmed to default to a
Temperature Limit Switch. For other uses of TS1-TLS1/AUX1 see section 7.8
TEMPERATURE LIMIT Switch / Back Step.
NOTE: Jumper TS1-TLS1/AUX1 and TS1-GND if the Temperature Limit Switch is not
used. Temperature Limit Switch supplied standard, with 300,600 and 1200 AMP SCR
Contactors and optionally with 1800 and 2200 AMP SCR Contactors.
(0(5*(1&<6723: This is a terminal strip connection which allows all control functions
to be reset upon opening of the Emergency Stop switch. The control can not be re-initiated
automatically upon release of the switch and must be re-initiated through the re-closure of
the pilot circuit. While in the Emergency Stop condition, the control will flash an ERROR
Code "E.S." in the DATA Display (4) until the condition has been cleared.
NOTE: Jumper TS1-ES1 and TS1-GND if the Emergency Stop Switch is not used.
Emergency Stop Switch is not supplied with the control.
