Shanghai Mitsubishi GPS-II/GPS-III/HOPE/LEHY-C Load Weighing Calibration Manual

I. GPS/HOPE Series Specific Calibration

1. No-Load Calibration

1. Position elevator at mid-floor (oil cup alignment)

2. Set MON(MON0) potentiometer to "2"

3. Adjust differential transformer spring until P1 boArd displays "65-70" (Ensure cabin empty)

4. Toggle LD0/LD1 switch to LD0 → Data saved when display stabilizes

2. Half-Load Calibration

1. Position elevator at mid-floor

2. Set MON(MON1) potentiometer to "2"

3. Manually pull weighing plate to achieve "≈114" (Displayed as "14.")

4. Toggle LD0/LD1 switch to LD1 → Data saved when display stabilizes

3. Compensation Writing

1. Position empty cabin at bottom floor

2. Toggle FMS switch in high-speed mode → P1 display blinks

3. Immediately toggle DCB switch → Elevator ascends at 1m/s

4. Repeat ≥3 cycles (30-second intervals recommended)

II. LEHY-C Series Specific Calibration

1. No-Load Calibration (Voltage Reference)

1. Position elevator at mid-shaft

2. Machine Room Operation:

   • Adjust "ZERO" potentiometer to achieve 0.5V±0.02V between OUT+/-

3. Control Panel Operation:

   • Set SET1=6, SET0=2

   • Single SW1 toggle → Data saved when 7-segment stops blinking

2. Half-Load Calibration

1. Position elevator at mid-shaft with 50% load

2. Machine Room Operation:

   • Adjust "OUTPUT" potentiometer to 2.5V±0.05V

3. Control Panel Operation:

   • Set SET1=6, SET0=3

   • Single SW1 toggle → Data saved

3. Compensation Writing

1. Position empty cabin at bottom

2. Set SET1=0, SET0=7

3. Single SW1 toggle → Auto-ascend to top

4. Repeat 3 cycles (Compensation accumulates)

III. System Functions

Cross-Model Functions

Safety regulations:

●CAT III 1000V grade test leads must be used for voltage measurement

●It is strictly forbidden to enter the shaft during the compensation operation (the elevator will run continuously)

Note: Execute ECD-25 self-test after LEHY-C sensor calibration.
