3.9 Multiple Cabinet Power Up/Down Procedures
For all multi-cabinet MX Series configurations (MX30/2, and MX45/3), the following Power Up
(Turn on) and Power Down (Turn off) procedures should be observed.
3.9.1 Power Up Procedure
Follow these steps:
1. Turn on each of the Auxiliary units using the front panel circuit breaker, one at a time.
The exact order for turning on the auxiliary units is not important. Note that the bias
supplies of each of the auxiliary cabinets will power up but not the actual amplifiers. This
is because the auxiliary units are waiting for the turn on signal from the master unit.
2. Once all auxiliary units are on,
turn on
the
MASTER
unit
LAST
using the front panel
circuit breaker. The master unit will go through an initialization process and power up
itself plus the auxiliary units.
3. Allow 20 to 30 seconds for the turn on sequence to complete before attempting to
communicate with the system.
3.9.2 Power Down Procedure
The power-down / shutdown sequence for the system is the reverse of the power-up / turn-on
sequence. This means the MASTER unit is turned off FIRST. Once the MASTER shuts down,
all auxiliary units’ main AC input power contactors will open up automatically. They still need to
be turned off individually using the front panel circuit breaker. This will shut down their bias
supplies as well.
Follow these steps:
1. Disconnect the EUT by opening the MX15 output relay. Use the Output On/Off button
on the master unit front panel or send the “OUTPUT 0” command over the bus to do so.
2.
Turn off
the
MASTER
unit
FIRST
using the front panel circuit breaker. The master unit
will disengage the main AC power input contactors of all auxiliary units at this time.
3. Next, turn off each of the Auxiliary units using the front panel circuit breaker, one at a
time. The exact order for turning off the auxiliary units is not important.
