GV5/GV3.5 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER
VERSION 0.2 2014-07-23 PAGE 3.2.109
Hardware Configuration
The
Hardware Configuration
page (see Figure 3.2.92 ) allows configuration of the transmitter for any
installed hardware that has optional variations (e..g, quantity of exciters or LVPS modules, fan speed) or
is non-standard (e.g., UPS or audio processor).
NOTE
: These settings are established at the factory based on the configuration that existed at time of
shipping. Changes to these setting are only necessary if hardware is added or removed by the user. For
all changes, press
Apply
to save the change or press
Cancel
to abort the change.
NOTE
: You can also configure transmitter hardware using the controller UI (see Configuring Installed
Hardware, on page 3.2.120 ).

Installed Exciter(s):
Select
Single (A)
or
Dual (A/B)
, depending on the number of installed exciters.
If you have upgraded your transmitter to dual exciters, you may have already been prompted to
change this configuration.
 LVPS Hardware: Select
Single LVPS: A
or
Dual LVPS: A/B
, depending on the number of installed
LVPS modules. The standard transmitter ships with dual LVPS modules.

LVPS Voltage:
Set the default LVPS voltage (between 35 and 53 V) used by the transmitter during
normal operation. Under fault conditions, if the LVPS voltage requires an increase, the control
system automatically increases the LVPS voltage, then decreases it back to the set value when the
fault condition clears. This setting should not require adjustment.
 Fan Speed: Set the default speed of the transmitter’s cooling fans to a percentage between 63 and
100% of the maximum speed during normal operation. The 63% default corresponds to a fan
voltage of approximately 31 V. A 100% setting corresponds to approximately 48 V. Under fault
conditions, the control system determines if an increase in fan speed is required and automatically
adjusts the fan speed.
NOTE
: The transmitter control function automatically adjusts fan speed to ensure adequate cooling
based on all operating conditions. As a result this setting should not require adjustment. Increasing the
fan speed will allow for cooler transmitter operation, but will also decrease efficiency and increase
acoustic noise levels. A 20% reduction in fan speed can yield up to 5 dB improvement in acoustic noise
from the transmitter, as well as decrease power consumption (i.e., utility costs) and extend the
operating life of the cooling fans.
