Introduction

The front panel has a high visibility display configurable up to 8 digits which can
show the process variable, using 4 ½ digits, and the totalization. During configuration, the
display shows mnemonics and parameter values. The leds and the display can be used
as a visual indication of alarm or they can be associated to the alarm outputs. So, there
are up to seven alarm indications available (four alarm modules together with the display
and leds). The alarm outputs can be configured, independently, to operate with latch,
demanding the operator acknowledge by means of the front panel keys in order to
deactivate them after the process variable returns to normal condition.
One retransmitter output is available to provide a linear output signal from 4 to 20
mA, 1 to 5V or 0 to 10V proportional to the input process variable being measured. This
signal allows the retransmittion of the variable to a distant location. When using the
analog output, up to three alarm modules can be used.
