9.5.2 RETRACTION OPERATION - MAINTAINED CLOSURE - [

(THREE STAGE FOOT-SWITCH RETRACTION ADDITION
)
EN1000/EN1001 Series Controls incorporating ROM #619016-002 Revision “R” or later
will have the following Retraction Feature added.
If [
H!=!
] is set to [
"+
] the control will now enter this new Retraction Mode. This Retraction
implementation is different from [
;!:!
]=07 or [
;!:!
]=08 in that it uses one foot switch that
has a maintained/latched contact that the control uses to turn on the Retraction Output V3.
The software has a power-on interlock of the V3 output to block the V3 from turning on with
power on. This new feature, simple as its operation may be, will help users implement this
type of retraction without putting high voltage on one pole and/or in the same conduit as the
low voltage foot switch wiring.
The valve output between TS1-SV5 and TS1-SV6 is enabled by closing the TLS1/AUX1
to GND switch. TS1-SV5 and TS1-SV6 remains on during and after a weld as long as the
switch remains closed.
Successive schedules can be used with Retraction.
When the RETRACTION valve is on, the control may not be placed into the Program mode.
The dial plate indication of the third valve output (RETRACTION VALVE) will not indicate
the status of Process Output.
WARNING
The jumper on TS3 on Terminal Strip/ Firing Board A/N 410319 must be installed as
JB, to connect terminal 1 to VL1, as indicated by "JB" printed on the board.
Moving this jumper will bypass the Valve Control Relay, which normally prevents
valve activation until a weld sequence is initiated. Since this valve may now be activated
without energizing the control relay, care MUST be taken to insure safe operation.
