6.5 Non-Routine Calibration
The non-routine calibration may involve removing the front or top cover of the
power source. Use extreme caution when performing any of these tasks while
the system is connected to AC mains and/or powered up.
6.5.1 Power Source Gain Adjustment
For any MX configuration that requires two or more amplifiers to be operated in
parallel for increased current output, the amplifier gains must match as closely
as possible to ensure equal current sharing. If an unbalance exists between
amplifier outputs, one or the other amplifier will deliver more current and may
run into its current limit protection before full output power can be attained.
This procedure details the gain adjustment. Generally, MX units are shipped
with the gains already set correctly so this task should only be undertaken if an
amplifier has been replaced or if two MX units are to be combined that were not
originally shipped from the factory as such.
To make this adjustment the front cover must first be removed to get access to
the power module output terminals. If the power system to be adjusted is an
MX45-1, the procedure involves matching the output voltage of the B and C
power modules to the A module. Proceed as follows:
