TS1-FS7/SS1 and TS1-FS11/SS3 can also be used for a set of initiations configured for
ANTI-TIE DOWN. When programmed via the EXTENDED FUNCTIONS [SS] ANTI-TIE
DOWN [02] these terminals become inputs for ANTI-TIE DOWN. Use two single pole
normally open Push Button Switches connected from TS1-FS7/SS1 and TS1-FS11/SS3 to
TS1-GND. See the sketch below.
To program the control for ANTI-TIE DOWN operation, the EXTENDED FUNCTION [SS]
mode must be selected. See Section 7.3 EXTENDED FUNCTIONS. Use the SCHEDULE
SELECT Push Buttons (20 & 21) and SCHEDULE Display (22) to select [SS]. With the
control in the PROGRAM Mode enter a [02] into the DATA Display (4) using DATA Push
Buttons (5 & 6). As typical of other data entry the ENTER Push Button (29) must be de-
pressed to load the desired data.
With ANTI-TIE DOWN operation the machine electrodes will retract if either or both
initiation push buttons are released before the end of squeeze time.
The initiation terminals FS3, FS7/SS1, and FS11/SS3 may be connected as follows to
provide both anti-tie down and single contact initiation (with lockout) as follows:
With this system the dialed schedule will initiate by either initiation mode.
NOTE: The ANTI-TIE-DOWN feature requires that both of the operators hands be on the
push buttons during the squeeze time. therefore, if squeeze is programmed more than once
in a chained sequence the pushbuttons must be held until the end of the last programmed
squeeze time. Otherwise the electrodes will retract prematurely. The addition of a
programmed valve will also cause the electrodes to retract prematurely, if the push buttons
are not held. ANTI-TIE-DOWN is not available when operating the control in the seam
mode.
