HM1734-WM Strain Gage Input Module
OUTPUT TAG DESCRIPTIONS
CALMODE
Used for initial installation. All math is disabled, weigh value is not scaled, leaving raw A/D value.
Value = 2,090,000 to 2,100,000 at normal zero (at rest state).
RUNMODE
A/D values scaled with math in ladder logic
Factory cal setting 100,000 counts = 2MV/V
CLEAR TARE CH1/CH2 Bit
Clears internal tare value for “zero state”.
Useful when troubleshooting load cell wiring or other failures.
TARE CH1/CH2
Sets A/D value to zero.
READ ADTRIM BIT
(HELM Factory setting only).
SET-TO-CH1 Bit
Used for one channel operation where a faster sample speed is required.
1 = 2msec (max speed)
0 = 4msec (max speed-default)
FREQUENCY BITS
Used to set sample rate and filter options.
With no bits set: Sample = 100msec.
Set one bit only.
Note: For one channel operation, sample rate is at bit selected.
For two channel operation, sample rate is 2 times bit time selected.
