SERVICING THE AT10.1
Replacing the dc surge suppressor (VR1)
Turn off and remove all power to the AT10.1. Remove the Plexiglas
safety shield. Disconnect the battery from the output terminals TB1(+/-).
Remove the hardware from the output terminal TB1(+), and remove the
lead of the dc surge suppressor. Install one lead of the replacement surge
suppressor. Replace the other wires and the hardware. Repeat for the
output terminal TB1(-). Tighten all hardware.
NOTICE
The dc surge suppressor is not polarized.
Replacing the dc EMI filter networks (VR6/C4, VR7/C5)
Replace these networks as assemblies. Do not replace individual parts.
Turn off and remove all power to the AT10.1. Remove the Plexiglas
safety shield. Disconnect the battery from the output terminals TB1(+/-).
To replace the network VR6/C4, remove the hardware from the output
terminal TB1(-), and remove the lead of the network. Cut the plastic wire
ties holding the assembly tight against the I/O panel. Install one lead of
the replacement network. Replace the other wires and the hardware.
Repeat for the other lead of the network on the ground terminal. For the
VR7/C5 network, use the above procedure, but start with the lead on
TB1(+). Tighten all hardware. Replace cut wire ties if possible.
NOTICE
The dc EMI filter networks are not polarized.
Replacing the power supply ballast resistor (R3)
Shut down and remove all power to the AT10.1. Remove the Plexiglas
safety shield. Disconnect the battery from the output terminals TB1(+/-).
Locate the power supply ballast resistor (R3) near the I/O panel (TB1). In
12 & 24 Vdc units, R3 is installed at the top right corner, connected to
E17 and TB1(+). In 48 & 130 Vdc units, R3 is mounted on the bracket
behind the I/O panel. In 130 Vdc 6Adc units, R3 is comprised of an
assembly of two (2) resistors connected in series, mounted to the bracket.
Disconnect the lead of R3 connected to TB1(+) and replace it with the
corresponding lead of the replacement power resistor. Remove the other
lead of R3 from terminal E17 on the I/O panel and replace it with the
remaining lead of the replacement power resistor. Tighten all hardware.
In 12 & 24 Vdc units, tuck the new R3 resistor behind the I/O panel so
that leads are properly spaced. In 48 & 130 Vdc units, remove the screws
that mount the old R3 resistor(s) to the bracket, and replace with the new
resistor(s). Tighten all mounting hardware and restart the AT10.1.
