Power-Up Procedure; Front Panel Operation - Partlow MRC 7000 Installation, Wiring, Operation Manual

3.4.1 POWER UP PROCEDURE
Step 1
Verify that all electrical connections have been properly made before applying power to the
instrument.
Step 2A - For instruments with software revision R2.99 and below
Upon power up, 7XXX will be displayed (X representing digits), then XXXX, then XXXX,
identifying the twelve digit model number as defined in the order matrix. Next, the EPROM
part number will be indicated P-XX. After the EPROM part number, the software revision level
will be displayed in the format rX.XX then tSt1, tSt2, tSt3 will be displayed while Test 1
through 3 are executed automatically. Upon successful completion of these tests, CtrL or oFF
will be displayed for about three seconds. The mode displayed will be the mode that the
instrument was in when the power was turned off. During this time the operator may select
another mode (Tune, Manual, Enable) or non-operational mode (Test, Program, Cal).
Step 2B - For instruments with software revision R3.00 and above
Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show
the instrument is "alive". Then 7XXX will be displayed (X representing digits), then XXXX,
then XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the
EPROM part number will be indicated P-XX. After the EPROM part number, the software
revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power
Up, PAPu, in Program Mode is set to 0, pens go to "home" position on power up). During this
display, the decimal point after the "P" will blink to show the mode is active. Upon successful
completion of this routine, CtrL or oFF will be displayed for about three seconds. The mode
displayed will be the mode that the instrument was in when the power was turned off. During
this time the operator may select another mode (Tune, Manual, Enable) or non-operational
mode (Test, Program, Cal).
Step 3
If any error messages are displayed, refer to Section 5.6 (page 60) for a definition of the
error message and the required action.

3.5.1 DIGITAL DISPLAY AND STATUS LED'S
The digital display provided for each pen has 4 digits and a decimal point. Each digit has
seven segments and is capable of producing numeric characters from 0-9 and certain alpha
characters. The digital display is used to provide indication of process variable as well as
displaying codes used for configuration and operation of the instrument. The display includes
the following Status Indicator LED's;
MAN Amber
OUT1 Red
OUT 2 Amber
ALRM Red
C Red
F Red
U Red
SP Green
- Red
RAMP Red
SOAK Red
SEG 1-6 Red
Refer to Figure 1-2 (page 7) for the display features illustration.
