Getting started
After completing the installation of both MCULOG control unit and the MSP900SH transmitter, the next stage is to switch on.
1. Familiarise yourself with the front panel fascia.
Front Panel Fascia of MCULOGW
Key to figure:
c 4-line LCD with backlight.
d Keypad with 6 function keys.
e Status LED – flashes once per second if okay.
Note: The model type is shown on the LCD display in the
bottom, right-hand corner.
3. Familiarise yourself with the primary display.
Primary Display
Key to figure:
1. Off-line/on-line status. (Locked padlock = on-line)
(See page 10)
2. Digital input status. (o = de-energised, = energised)
3. Measured variable (P.V.) and units of measurement.
4. Bar graph of 4-20mA output of MCULOG.
5. Relay (RL) status. (o = de-energised, = energised)
6. Digital communication in progress. (Absent if idle)
7. Shows specific model type.
2. Switch on the MCULOG by applying the power.
Wait for the primary display (inset, right) to
appear.
During this time, the MCULOG will read parameters
from the MSP900SH transmitter.
If being used for the first time, it will prompt for the
Bottom Reference of the MSP900SH transmitter
and then automatically set-up the 4-20mA output
span over this range. If you do not want to
commission the system now, simply switch off
the power – the same prompt will then re-appear
when switching on the next time.
If you are commissioning the system, edit the
Bottom Reference with the arrow-keys and then
press the yellow key to confirm the value. The
Bottom Reference can be changed at a later stage
but it is better to get it correct now. Should you
press the red (ESC) key, the MCULOG will continue
and the Bottom Reference prompt will re-appear
when switching on the next time.
Once the start-up is completed, the primary display
should appear, showing the measured depth of the
liquid in the tank. The value on the primary display
is the P.V. (Primary Variable).
Note: If a “Find Instrument” screen appears and
remains, power off. Check the cabling and then try
again. If the problem persists, follow the on-screen
prompts until the primary display appears.
