PGM Program signature found in memory.(Normally On)
If this light does not come on, it means that the main CNC program package was not found in
memory or that the auto-start switch was not set. Check that switch S1-1 is on and the EPROM
is plugged in.
RUN Program Running Without Fault Exception. (Normally On)
If this light does not come on or goes out after coming on, there is a problem with the microproces
sor or the software running in it. Check all of the buss connectors to the other two PCBs and
ensure all three cards are getting power.
There is 1 two-position DIP switch on the processor PCB labeled S1. Switch S1-1 must be ON to auto-start
the CNC operational program. If S1-1 is OFF, the PGM light will remain off.
Switch S2-1 is used to enable FLASH. If it is disabled it will not be possible to write to FLASH.
The processor connectors are:
J1 Address buss
J2 Data buss
J4 Serial port #1 (for upload/download/DNC) (850)
J5 Serial port #2 (for auxiliary 5th axis) (850A)
J3 Power connector
J6 Battery
MEMORY R ETENTION B ATTERY
The memory retention battery is initially soldered into the processor PCB. This is a 3.3V Lithium battery that
maintains the contents of CMOS RAM during power off periods. Prior to this battery being unusable, an alarm
will be generated indicating low battery. If the battery is replaced within 30 days, no data will be lost. The
battery is not needed when the machine is powered on. Connector J6 on the processor PCB can be used to
connect an external battery.
VIDEO K EYBOARD WITH F LOPPY
The VIDEO and KB PCB generates the video data signals for the monitor and the scanning signals for the
keyboard. In addition, the keyboard beeper is generated on this board. There is a single jumper on this board
used to select inverse video. The video PCB connectors are:
P1 LOW VOLTAGE POWER SUPPLY PCB (860)
P3* KEYBOARD INFO. (700)
P4 ADDRESS BUSS
P5 DATA BUSS
P10 FLOPPY DR. POWER
P11 SPARE
P12 FLOPPY DR. SIGNAL
P13 VIDEO SIGNAL (760)
J9 RS422 B
J13 SERIAL DATA (850)
