Regenerative Translator Turn On Procedure
Instruction Manual, Rev. 0 18
Initial On Site Turn On Procedure
After the Innovator CXB Series tray or trays are installed and all input, output and AC
connections are made, the system is ready for the initial on site turn on. Check that the
output of the CU5, CU30, CU50, CU100, or CU125 tray is connected to an appropriate rated
load or to the digital mask filter and the antenna for your system. If your system is a CU250
or higher power system, check that the output of the amplifier tray or the combiner assembly
is connected to an appropriate rated load or to the low pass filter, the digital mask filter and
the antenna for your system. Check that the main AC power to the System is ON.
If you have a CU5, CU30, CU50, CU100 or CU125 system, push ON the switch located on the
rear panel of the tray above the AC power jack. The large fan mounted on the rear panel of
the tray should operate. If your system is a CU250 or higher power system, switch ON the
ON/OFF circuit breakers located on the rear panel of the amplifier tray(s) mounted on each side
of the AC input power jack. The two fans mounted in the amplifier tray should operate.
The Operate/Standby LED and Status LEDs on the CU5, CU30, CU50, CU100 or CU125 should
be Green indicating the system is in Operate and performing normally. The Operate/Standby
LED showing Amber indicates the System is in Standby. The Status LED showing a blinking Red
LED indicates a Fault is occurring now. The Status LED showing Amber indicates that a Fault
occurred since the last time the Fault indications were reset.
If your system is CU250 or higher power, the Enable LED and Status LEDs on the 250 or 500
Watt Amplifier Tray should be Green indicating the system is in Operate and performing
normally. The Enable LED showing Amber indicates the System is in Standby. The Status LED
should be Green indicating no faults in system. If the Operate/Standby LED shows Amber it
indicates that the System is in Standby. If the Status LED is blinking Red it indicates a Fault is
occurring now. If the Status LED shows Amber it indicates that a Fault occurred since that last
time the Fault indications were reset. The output power is factory set according to customer
request and does not need adjusted. If a problem occurs, call Axcera field support at 1-724-
873-8100 for information on modifying the power level of the system.
NOTE: The RF System Interlock is provided on J12, a D connector, located on the rear panel
of the CU3, CU30, CU50, CU100 or CU125 tray. The RF System Interlock at J12-5
provides the customer with a means of connecting the system to protection circuits,
for the loads, thermal switches, combiners, or the antenna, in the output of your
system, that will place the system in Standby if the protection circuit opens. The
Reject Load Interlock at J11-6 provides the customer with a means of connecting the
system to protection circuits, for the reject load in multiple amplifier systems, which
will place the system in Standby if the protection circuit opens. If the interlocks are
not used in your system, a plug with a jumper from J11-5 to J11-9, ground, for RF
system Interlock and another plug with a jumper from J11-6 to J11-9, for Reject Load
Interlock, need to be connected. These jumpers provide the RF System and Reject
Load Interlocks, which allow the system to go to operate. Without the jumpers, the
system will remain in Standby.
