SECTION IV - SYSTEM FUNCTIONS
4.7
SENSOR 1, 2, 3 FAULTS
The M-227 has 3 separate inputs that the user can define for creating a fault
condition based on some external problem. The most common is connecting a gas
analyzer(s) to the M-227 to detect excessive Oxygen in the I.D. purge of a weld.
The user must make these connections and uses the SET-UP screen (see 5.8) to
define what a fault is for this external input.
4.8
SET-UP FUNCTIONS
The following SET-UP functions provide some customizing and calculating
features to enhance system performance:
1.
CALCULATE - Calculates TUNGSTEN LENGTH, IPM to RPM
conversions and WELD TIME.
2.
WELD-SELECT - The M227-RP may select up to 4 pre-determined weld
schedules from memory. This function defines the schedules that are picked.
3.
COOLANT FAULT - Used to enable or disable Coolant Fault whether or
not a M227/207-CW or M207-CW is connected.
4.
REV - Used to display the SOFTWARE REVISION of a particular M-227.
Depending on intended use, M-227’s may have different software revisions.
5.
PRINT EMM - Used to print a copy of the EMM memory.
6.
AMP - TIME - Used to change the last significant digit of Level Current or
Level Time from whole numbers to tenths (000 to 000.0).
7.
ARC V FLT - Used to de-activate STUB OUT and HIGH VOLT faults
These faults are usually needed to be turned off for manual welding.
8.
SENSORS - Activates and defines EXTERNAL Fault inputs (see 5.8).
9.
PRINTER - Used to select AUTO or MANUAL print mode.
10. OSC SPEED - Used to set the speed that the OSC IN Key and OSC OUT
key move the Oscillator Steering.
11. DATE RESET - Used to reset the DATE.
12. AVC JOG SPEED - Used to set the speed of the AVC JOG UP and AVC
JOG DOWN. Primarily used to refine Touch Start Operation.
13. OPERATOR I.D. - Allows the Operator to enter his name or ID number.
Once entered it will be printed on all copies of weld schedules.
14. POWER SUPPLY SERIAL NUMBER - Allows entry of Power Supply
Serial #. Once entered it will be printed on all copies of weld schedules.
