4. CONTROL and INDICATION COMPONENTS of DATA LOGGER
4.1.
Indication of power and state of output ALARM OUT
Indication is performed visually by LED diodes located at case side next to power terminals (see
Drawing). Green LED indicates the presence of power voltage, red LED activity of output ALARM OUT.
4.2.
Display and keyboard
Left from display are three indication LED diodes:

Power - indication of presence of power voltage

Memory (orange) - indication of exceeding of adjusted memory occupation limit

Error
–
lights, if configuration violence of data logger appears or error in self test
appears
Display is dual line, display can be controlled by means of four button keyboard located next below it
(buttons MENU, , ,ENTER). After connection of data logger to power self test of several internal
voltages is performed first. If everything correct, data logger starts to display values. Figures below are
valid for MS6D. For data logger MS6R only location of the keyboard differs.
Display after connection power to data logger.
Datalogger model and name is displayed for several seconds.
Then data logger evaluates self test of internal voltages. If
everything correct, data logger starts to display values. If self test
is not correct, data logger reports Self Test Error with specified
voltage, which is not correct (power voltage, internal battery and
source of negative voltage). The failure is necessary to fix. If
specified error message is confirmed by pressing ENTER key,
data logger goes on to basic display.
Basic display on the LCD
In basic display upper line displays user specified name of
measuring point, adjusted from user program. Lower line
displays measured value with physical unit respective state of
input channel. All active channels can be checked by keys
, .
Error message can occur instead of measured value. Binary
inputs display at the whole LCD bottom line user defined
description of state closed/open. In case value is not available or
is not correct error message is displayed
