Initial On Site Turn On Procedure
After the Innovator CHVB 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 CHV200B tray 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 CHV400B and
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 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 or KTECH receiver tray, 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, push On the ON/OFF button, located on the left side of
the top panel of the UPS. The UPS is mounted behind the removable blank panel, located
immediately above the exciter/driver tray, which is held in place by four #10 Phillips head
screws.
If you have a CHV200B 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 CHV400B and higher power system, switch ON the ON/OFF
circuit breaker(s), 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 CHV200B 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 a CHV400B and higher power, the Enable LED and Status LEDs on the 500,
750 or 1000 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 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 J11, a D connector, located on the rear panel
of the CHV200B tray. The RF System Interlock at J11-5 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.
