USING BOTH TEMPERATURE LIMIT SWITCH AND BACK-STEP FUNCTION
If a Temperature Limit Switch is being used, it can be connected to TS1-NW1 and TS1-GND.
This is the External Weld/No Weld input. If this switch is open, the control will be in a NO
WELD condition.
The Back-Step Switch replaces the TLS operation. Alternatively, the Temperature Limit Switch
should be connected in series with the Water Flow Switch (WFS) or connect the Temperature
Limit Switch to the External Weld/No Weld input (NW1) while using the BACK-STEP option.

The EN1000 and EN1001 provide an output that can be useful when the operator or the system
needs feedback from specific parts of the welding sequence, such as: major or minor error
conditions to machine controls, shunt trips, or indicator lamps. Some PROCESS OUTPUTS
may result in changes of the control sequence, status, fault, or major or minor error conditions.
These changes are intentional with the objective of providing designers with complete flexibility.
See Table 5-6 for the data codes available.
To use any PROCESS OUTPUT mode:
1. Put the control in PROGRAM mode.
2. Use SELECT to find

Valve 3 may be connected to the shunt trip of a circuit breaker. Under certain conditions as
listed below, when a shunt trip breaker is tripped, it is the same as removing power from the
control. Most breakers can be equipped with a 110 VAC input shunt trip device. Refer to Section
4.3 and the appropriate Wiring Diagram.
Installation of Jumper JB between TS3-1 and TS3-VL1 will allow
programming of Valve 3 output per Table 5-6.
Exercise caution when programming since the result of its activation
could cause a personnel hazard.
The jumper between TS3-1 and TS3-VL1 is necessary to bypass the Valve
Control Relay normally incorporated in the standard operation of Valve 3.
Table 5-6 summarizes all PROCESS OUTPUT codes. Detailed descriptions of each PROCESS
OUTPUT follow the table.
