Measures exactly 25 cm x 25 cm x 15 cm with a net unit weight of 1.7 kg (approximately 6.61 lbs), making it an incredibly compact processor module for multi-axis management.
The unit accepts a nominal input of 24 Volts DC. Users must adhere to the maximum cable size of 1.5 mm². The I/O bus supply has a maximum overall capacity of 52W. Do not touch electrical connection points while the device is powered on, as improper use could result in high discharge currents and voltages. If you have downloaded the PDF manual or

: Adjust the internal acceleration/deceleration potentiometers to smooth out step-change commands. This prevents harsh hydraulic shock (water hammer) in your plumbing. Troubleshooting Common Faults Potential Root Cause Corrective Action No pressure output No power supply to Pin A. Check line fuses and confirm 24 VDC at the plug. Pressure does not change Missing or disconnected command signal. Measure voltage across Pin D and Pin E with a multimeter. Erratic pressure oscillations Trapped air or excessive tank backpressure. Bleed the valve assembly; check for obstructions in Port T. Valve runs excessively hot Solenoid current is too high or fluid is degraded.
