Connecting to Power
Note that the AC voltage source MUST be rated as either:
◆
120 VAC, 20 amps, 50/60 Hz
◆
230 VAC, 10 amps, 50/60Hz
Line voltage selection is automatic. For 220V input
application, remove the male plug on the supplied power cord
and replace it with one that fits the local AC receptacle, or an
adapter cable can be locally manufactured. See Figure 3-3 for
the correct plug termination.
EXTERNAL
INTERLOCK CONNECTIONS
The INTERLOCK connector on the front panel of the Control
Unit enables interconnection of x-ray enclosure doors and/or
external warning devices with the internal safety interlock
circuitry of the system. Figure 3-4 illustrates the two circuits
provided for this purpose.
Pins “ A ” and “ B ” are used to connect enclosure door switches.
When pins A and B are properly connected, x-ray generation
is possible only when the enclosure doors housing the
Tubehead are shut. Note that pins
“ A ” and “ B ” of the
INTERLOCK connector must form a closed circuit to operate
the X-ray unit. If no external switch interlocks are
incorporated, a jumper (provided) must be installed across
pins
“ A ” and “ B ” to form this closed circuit.
Pins “ C ” and “ D ” provide a switch closure to operate warning
devices such as lights, sirens, or other types of external
warning signals. These signals warn all personnel that x-rays
are being generated.
Pins E and F are for use with optional LORAD pre-warning/
warning devices.
! WARNING !
Voltage is present at pins “A” and “B”
of the INTERLOCK when the unit is
powered up. Ensure power is OFF
before making any external
connections or while installing the
jumper.
