ATSC Transmitter/Regenerative Translator Turn On Procedure
Instruction Manual, Rev. 1 27
Initial On Site Turn On Procedure
After the Innovator CX Series drawer or drawers 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 CU0TD-1 thru CU0TD-5 drawer is connected to an appropriate rated load or to
the digital mask filter, low pass filter and the antenna for your system. If your system is a
CU1TD-1 or higher power system, check that the output of the amplifier drawer or the
combiner assembly is connected to an appropriate rated load or to the digital mask filter,
low pass filter and the antenna for your system. Check that the main AC power to the
System is ON. If your system contains an optional ASI to S310 converter module,
K-Tech receiver drawer or Axciter, check that they have AC connected to them and that
they are turned ON. NOTE: If your system is mounted in a cabinet and contains an Optional
UPS, check that the ON/OFF button, located on the left side of the top panel of the UPS is On.
The UPS is normally mounted behind the removable blank panel, located immediately above
the exciter/driver drawer, which is held in place by four #10 Phillips head screws.
If you have a CU0TD-1 thru CU0TD-5 system, push ON the switch located on the rear panel
of the drawer above the AC power jack. The large fan mounted on the rear panel of the
drawer should operate. If your system is a CU1TD/TD-1 or higher power system, switch ON
the ON/OFF circuit breaker(s), located on the rear panel of the amplifier drawer(s), mounted
on each side of the AC input power jack. The two fans mounted in the amplifier drawer
should operate. Place the system in Operate. The Operate/Standby LED and Status LEDs on
the CU0TD-1 thru CU0TD-5 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 an Event (Fault) is occurring
now. The Status LED showing Amber indicates that an Event (Fault) occurred since the last
time the Event (Fault) indications were reset.
If your system is CU1TD/RD-1 or higher power, the Enable LED and Status LEDs on the
Amplifier Drawer 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 Events (Faults) in the 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 an Event (Fault) is occurring now. If the Status LED shows Amber it indicates that
an Event (Fault) occurred since that last time the Event (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 724-873-8100 for information on modifying the
power level of the system.
NOTE: The RF System Interlock is provided on J12, a 15 position “D” connector, located on
the rear panel of the CU0TD-1 thru CU0TD-5 drawer. 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 is provided at J11, a 9 position “D” connector. 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 J12-5 to J12-15, 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.
