| Symptom | Solution | |---------|----------| | Won’t power on | Charge for 30 minutes; try different cable | | Image always white | LEDs too bright – dim them; reduce object reflectivity | | Can’t focus on flat object | Place object on a contrasting background (e.g., dark paper) | | Buttons unresponsive | Use pin to press Reset hole near SD slot | | Saved photos look pixelated | Reduce digital zoom; use focus instead of zoom | | “SD Error” on screen | Reformat SD card (Settings > Format) or replace card |
The standout feature of the Altoc VTM 10 is its universal input stage. Unlike competitors that require different modules for voltage, current, and temperature, the VTM 10 adapts. This reduces spare part inventory by 60% for many factories.
Step 1: Mount the Unit Snap the Altoc VTM 10 onto a grounded 35 mm DIN rail. Ensure at least 20 mm clearance above and below for airflow.
Step 2: Power Connection
Warning: Do not apply AC voltage to the DC variant—this will destroy the internal power supply.
Step 3: Input Wiring (Depends on Sensor Type)
| Sensor Type | Terminal A (IN+) | Terminal B (IN-) | | --- | --- | --- | | 0-10 V voltage | Signal + | Common / GND | | 4-20 mA current | Signal + (via 250Ω internal shunt) | Common | | Thermocouple Type K | TC+ (positive lead) | TC- (negative lead) | | Pt100 (3-wire) | White (sense+) | Red (excitation) and White (return) | altoc vtm 10
For RTDs: Ensure you enable the appropriate wire configuration in the software. Default is 3-wire.
Step 4: Output Wiring
For current output: Connect to a load resistor (e.g., 250Ω for 1-5 V input at PLC). Max load: 600Ω. | Symptom | Solution | |---------|----------| | Won’t
Step 5: RS-485 (Optional)
Set the Modbus address (1-247) and baud rate (9600, 19200, 38400) using the Altoc software.
Step 6: Initial Power-Up Apply power. The green LED should flash once, then remain steady. A red LED indicates an input error (e.g., sensor break). Step 1: Mount the Unit Snap the Altoc
