PRESSURE SWITCH – This feature is used to make the control wait if the required pressure
has not been reached while in the SQUEEZE interval as follows:
After initiation, the control advances through
SQUEEZE. If the Pressure Switch is open
(pressure not sufficient), the control waits,
and the SQUEEZE LED flashes at the end
of SQUEEZE. When the Pressure Switch
closes (pressure is sufficient), the flashing
stops and the control begins to WELD and
completes the sequence.
If the Pressure Switch interrupts the sequence for an extended period, the display will flash

15. This error will not terminate the sequence. Once the Pressure Switch closes,
the sequence will continue on to WELD and complete the sequence. See Section 4.3.2.
If a Pressure Switch is not used, place a jumper (factory installed) between TS1-PS1 and
TS1-GND. Pressure Switch is not furnished with the control.
EN1000/EN1001 Series Controls with PROM firmware version 619016-002J or later will have
the following Pressure Switch function revised. As of this version, the Pressure Switch will be
ignored if WELD time is set to
0000
0000
00. This allows sequences that use features such as CLAMP &
WELD to only have the Pressure Switch checked for the WELD sequence. Before this version,
the Pressure Switch was checked after SQUEEZE in all schedules, including CHAINED
schedules.
TEMPERATURE LIMIT SWITCH – This feature is used to inhibit welding if the temperature
of the switching circuitry is above the rated operating temperature (149E F). If the Temperature
Limit Switch is open (over temperature), the control cannot be initiated until the Temperature
Limit Switch cools (resets/closes). If the Temperature Limit Switch becomes open during a
weld, the weld interval will continue until the end of WELD time; HOLD and OFF will execute
normally but a new sequence cannot be initiated until the Temperature Limit Switch cools and
resets (closes). In either of the above cases, the DATA display will show ERROR CODE
0101
0101
01
until the Temperature Limit Switch recovers its normally closed state; then the control will
return to normal operation.
If the Temperature Limit Switch is not used, place a jumper between TS1-TLS1/AUX1 and
TS1-GND.
EMERGENCY STOP SWITCH – When the Emergency Stop Switch is open, the control
stops any and all processes (all valves and firing pulses). While in the Emergency Stop
condition, the control will flash

E.S. on the DATA and SCHEDULE displays until the condition
has been cleared. If the execution of a schedule was interrupted by means of the Emergency
Stop Switch, the control will not re-initiate automatically (after the Emergency Stop condition
is removed). Upon release of the switch, it must be re-initiated by closing the Pilot Switch.
If the Emergency Stop Switch is not used, place a jumper (factory installed) between TS1-ES1
and TS1-GND. Emergency Stop Switch is not supplied with the control.
