MOD 30ML Front Face Familiarization
Lab

1.1
Foreword
Many processes involve flow control loops, whether they are in the food, pharmaceutical,
chemical, pulp & paper, mining or virtually any of the industries served by MODCELL
Multi-loop Processors. This lab is designed to help you learn the basic features of the
Application Builder, as well as how to easily demonstrate configuration of a PID loop.
1.2
Objectives
In this lab we will download a simple PID control database from a memory module to the
MOD 30ML controller and get familiarized with the controller’s front face.
Figure 1 .1.
MOD 30ML Front
Face
After completing this lab, you should know how to download a database from a memory
module to a MOD 30ML controller and operate standard PID control loop from the front
face.
1.3
Equipment Required
You need the following equipment for this lab:
1.
1 x MOD30ML
1-1
Training Manual
MOD 30ML Front Face Familiarization Lab
1.4
2.
1 x Memory module (2010PZ10000A) marked FACEPLATE (and loaded with the
FACEPLAT.CDB file)
3.
1 x Small flat screwdriver
Instructions
1.4.1 Before you power up the instrument
Step
1
Procedure
Make sure the SERV/RUN switch
under the front face is set to the
RUN position
Comments
This ensures that after a download the database
will be able to run.
This switch is located behind the front panel in the
NEMA 4 option. You will need to remove the
instrument from its housing to set it.
2
Make sure the switches on the
memory module are set to READ
ONLY and NORMAL
This ensures that the database stored in the
memory module is downloaded to the instrument
during a power-up sequence.
Normal = Transfers the database contained in the
memory module to the instrument.
Module Load = Transfers the database contained
in the instrument to the memory module
1-2
3
Loosen the retaining screw and slide
the instrument from the housing
CAUTION ! Ensure that the main circuit board is
supported at all times.
4
Install the memory module
With the catalogue number of the memory module
facing upwards, install the memory module onto
the connector of the main circuit board
5
Place the instrument back into the
housing and tighten the retaining
screw
You should see ******** appear for a short while,
then a flashing loop display with the tag FIC-100
and the alarm light.

Note: Active Diagnostics
An unacknowledged diagnostic condition is always indicated by flashing of the alarm
LED. The indication may also include a flashing display and a beep signal depending on
configuration. A dedicated alarm display provides information on all active diagnostics.
An example of the display with control key information is shown in the next figure. When
the alarm light indicates an alarm condition, press the alarm key to access the alarm
displays. Pressing the key repeatedly scrolls through a series of displays covering all
unacknowledged alarms and acknowledged alarms that are still active. Unacknowledged
diagnostics are always displayed first in the viewing sequence. See IB-1800R-OPR,
Section 3 for more information.
Figure 1 .2.
MOD 30ML Alarm
Abbreviated diagnostic message.
[UAK] indicates that the alarm is active and has not been
acknowledged. Press the ‘A' key to acknowledge the alarm. If
alarm is still active [ACT] appears. If alarm is no longer active
[CLR] appears, and this display is deleted upon exit. [RET]
indicates that the R/L key can be pressed to return to the
runtime displays.
[7] is the Diagnostic event code number.
[AOUT] [2] indicates the block type and number.
Use the block type and event code number to locate a
description of the diagnostic event in IB-23M601 Section 7.3.
For example, code 7 for the [AOUT] block indicates an AOUT
(module) error because the output circuit has reported an
output-too-high or output-too-low error.

1.4.5 Operating the Ramp keys
Objective: To manually set the control output to a value of 24.8%. During the following
procedure, if the time between key strokes is greater then 10 seconds, then the display will
automatically change back to the operating loop display. If this is the case, simply press
either the UP or DOWN key and select the character you wish to change using the FST
and SLO keys.
