Entron EN1000 series

The valve output between TS1-SV5 and TS1-SV6 is enabled by closing the TS1-TLS1/AUX1
to TS1-GND switch. This output remains on during and after a weld as long as the switch
remains closed.
SUCCESSIVE schedules can be used with MAINTAINED CLOSURE RETRACTION.
When the retraction valve is on, the control may not be placed into PROGRAM mode.
The Control Panel indication of Valve 3 output (retraction valve) will not indicate the status of
PROCESS OUTPUT.
The jumper on TS3 on Terminal Strip/
Firing Board A/N 410319 must be
installed as JB to connect terminal 1 to
VL1, indicated by “JB” printed on the
board (see Figure 9-13).
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.
