User Interface
CAUTION! BEFORE PROCEEDING, ENSURE THAT THE INSTALLATION INSTRUCTIONS HAVE BEEN
FOLLOWED CORRECTLY. FAILURE TO DO SO MAY RESULT IN AN ELECTRICALLY HAZARDOUS
INSTALLATION OR IRREPARABLE DAMAGE TO THE INSTRUMENT.
The MXD70 Series uses a high quality backlit 3¾” QVGA LCD to display the channel readings and
settings. This is accompanied by 5 control buttons whose function varies depending upon which
screen the user is viewing. The button function is indicated by the control section at the bottom of the
display. Also present are six Setpoint Status LEDs that when illuminated indicate which setpoint / relay
is active. Located between the setpoint LEDs there are two Alarm Status LEDs which provide clear
indication of a fault within the instrument.
The Front Screen
The MXD70 Series front screen has the capability of showing up to three sensor input channels. Each
channel shows the main sensor reading and two secondary readings which can be customised to the
users requirement. If only one channel is displayed on the front screen then the ability to show up to
two current output trends becomes available. Alternatively a current outputs trend screen is available.
See Setup Front Screen on page 15 for more information.
