4. Controller info
These data allow technicians to visualize MX 43 counters set to zero since the
last zero setting.
6. USB Key
The USB Key feature is only available in firmware (internal
software) versions 4.0 and higher.
1. Configuration
Define the recording parameters on the USB key and view the storage
capacity remaining.
A 4G key can record approximately 18 months of information from an MX 43
comprised of 32 detectors with a sampling frequency of 2 seconds and up to
100 events per day and per detector.
■ Data Logging:
- Stop: stop recording measurements on the USB key. Stop the USB key
from recording before removing it in order to transfer the measurements
recorded that day from the MX 43 memory.
- Begins recording measurements on the USB key at the frequency
defined by the Sampling Rate configuration (see below). The USB key
icon appears at the top of the main screen (see Figure 44) when the USB
key is present and the unit has begun recording measurements.
■ Sampling Rate: selection of the frequency of recorded measurements –
2 sec, 16 sec, 30 sec, 1 min, 2 min or 15 min. At any frequency setting, the
MX 43 unit saves the measurements in the internal memory every 2
seconds. For example, if the recording frequency is set at 30 seconds, the
unit will record on the USB key an average value from the previous 15
measurements.
■ FIFO (First In, First Out): defines the action to be taken when the USB key
is full.
- Yes: the oldest recordings (measurements and events) present on the
USB key will be automatically erased.
- No: when the storage capacity in use reaches 80%, the MX 43 will
display the message Replace the key as soon as possible. Once the USB
key is almost full (98% of the storage capacity used) the alert message
USB key is full will appear. The message Recording impossible will
appear.
■ Fault Relay Activation: defines the state of the default relay once the USB
key is at 98%, absent when recording is activated, unformatted or in writing
error mode.
- Yes: the default relay is activated.
- No: the default relay is not activated.
■ Bargraph / Message: when the USB key is present, a bargraph is
displayed, showing the storage capacity in use. 100% indicates that the
key is full. When the key is not present but the measurement recording has
