(1c) Date and Time
– Date is written in YY/MM/DD format, updated from the embedded computer Real
Time Clock (RTC) or public NTP server.
(1d) Local Area Network (LAN) IP address
, via DHCP or permanently assigned if behind firewall.
(1e) System Configuration
– Reports system configuration: MMA for MRI application support, MEA
for EMFC application support, or (as normally supplied from production inventory) MTA for
Test configuration.
(2) POWER Status Indicator LED
– Indicates that all internal power sources are within specification when
steady BLUE.
(3) LEVEL Status Indicator LED
– Magnetic field strength level TRIP (fast RED flash) or WARNing (75%
or greater of TRIP level, slow RED flash), otherwise steady BLUE if axial field levels are below
programmed thresholds.
(4) CONTROL Status Indicator LED
– Indicates that the Machine Control Computer (MCC) embedded
computer is operating normally when steady BLUE. Steady RED indicates an inoperative DSP engine.
(5) RESET Pushbutton
(momentary pushbutton switch) – A short press resets the unit from any state to the
initial
ACQUIRE
state. A long press (>5 seconds) will completely reset/reboot the MACS/D-X-ACR.
Approximately 45 seconds is required to reinitialize and re-acquire the geomagnetic/environmental field
baseline following a reset/reboot.
(6) RESET Pushbutton Indicator Light
– BLUE Solid indicates that the system is energized and in its normal
OPERATE
state and magnetic field levels are within TRIP and WARNing thresholds. BLUE Flash(ing) indicates
the system is in its baseline
ACQUIRE
sequence, prior to entering the
OPERATE
state, or in an Auto Reset
sequence. RED Flash(ing) indicates an
OVERLEVEL
TRIP condition. RED Solid indicates the system is
detecting and preparing to sequence a full system reboot, due to either a manual reset/reboot or an A.C. mains
power cycle or transient dropout.
(7) DISABLE Pushbutton
(momentary pushbutton switch) – Disables the active compensation and turns off
the Coil Driver Amplifier (CDA).
(8) DISABLE Pushbutton Indicator Light
– BLUE Solid indicates
OPERATE
state or Auto-Reset sequence.
BLUE Flash(ing) indicates
ACQUIRE
state. RED Solid indicates the system is detecting and preparing to
sequence a full system reboot.
