PROCESS OUTPUTS may be implemented through the use of EXTENDED FUNCTIONS
[EF]. This feature can be used to communicate specific process statuses or error conditions
to machine controls, shunt trips, or an indicator lamp. Please note that in this mode, valve
three can no longer be used for a valve output. It is possible to program EXTENDED
FUNCTION [EF] with different data parameters which may result in weld control sequence
status or fault or error conditions, ranging from major to minor. This provides the designer
with complete flexibility. See the table below for a list of the many data codes.
To program the control for any of the PROCESS OUTPUT Modes, the EXTENDED
FUNCTION [PO] Mode must be selected. See section 7.3 EXTENDED FUNCTIONS. Use
the SCHEDULE SELECT Push Buttons (20 & 21) and SCHEDULE Display (22) to select
[PO]. With the control in the PROGRAM Mode enter the corresponding code from the table
below into the DATA Display (4) using DATA Push Buttons (5 & 6). As typical of other
data entry the ENTER Push Button (29) must be depressed to load the desired data.
Valve three 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 5.2 CUSTOMER TERMINAL STRIP DIAGRAMS, 5.3 CUSTOMER
TERMINAL STRIP CONNECTIONS, and the Customer Wiring Diagram.
NOTE: As the valve three output may be energized at any time, caution must be
exercised in what this output is connected to and the results of its being energized. Also
the jumper on terminal strip TS3 on circuit board #2 (410319) must be moved so as to
connect terminal 1 to VL1 as indicated by "JB" printed on the board. This is necessary
in order to bypass the Valve Control Relay standardly incorporated into the normal
operation of valve three.
