13. Off Time LED – The number of cycles of time after release of weld pressure until sequence is complete.
(0-99)
S T A T U S I N D I C A T O R: (Front Panel)
1. Repeat LED – When illuminated, the weld sequence will keep repeating as long footswitch stages 1 and
2 are depressed. When dark, the sequence will operate one time only.
2. Weld LED – When illuminated, the pulse will be sent to the firing board. When dark, no pulse is sent.
3. Seam LED – When illuminated, the weld cycles (Up % + Heat Time + Dn % + Cool Time) will repeat
as long as footswitches 1 and 2 are depressed. When dark, the controller is in spot mode.
4. Tip Dress LED – When illuminated, the air pressure is removed from the bottom of the weld piston
causing the head to lower due to it’s own weight.
5. ST1 LED – When illuminated, the first stage of the footswitch has been activated.
6. ST2 LED – When illuminated, the second stage of the footswitch has been activated.
S T A T U S I N D I C A T O R S (PSIO Board)
1. LED D7 – When illuminated, the 5 vdc command to operate has been given to relay K1. (Weld solenoid
120 vac output).
2. LED D8 – When illuminated, the 5 vdc command to operate has been given to relay K2. (Mtr On
solenoid 120 vac output).
3. LED D9 – When illuminated, the 4 vdc command to operate has been given to relay K3. ( Tip Dr
solenoid 120 vac output).
4. LED D4 – Will pulse ON if the line frequency varies from the programmed value. (Set for 60 c.p.s.).
5. LED D5 – Will pulse ON if the line voltage fluctuates above or below specified limits. (To monitor
power input disturbances).
F U S E S
1. F1 - Fuses one side of the incoming 120 vac. (1A 250V 312).
2. F2 – Fuses the 16 vac to CPU power supply. (1A 250V 312)
