Pump control unit Hägglunds ICp

Hägglunds ICp is a standalone solution for control of one hydraulic pump. The pump can be controlled without feedback, using the ICp as an amplifier or locked into closed loop control using either work pressure or swash angle as input. The pump solenoid coils are connected to ICp, which in turn is connected to the control system or a control panel. ICp can monitor different values of the system, sending warnings or alarms if any signal exceeds the allowed interval. Optional signals include temperatures, oil level, flow, digital input signals for monitoring and digital outputs for feedback. Configuration of ICp is done via Bluetooth and the Hägglunds ICp Mobile App available for both Android and iOS. 2.1 Galvanic isolation ICp has galvanic isolation between control and I/O side. The control side feeds USB, Bluetooth, display and main processor. The I/O side feeds pump control outputs, digital, analog and Pt100 connections. 2.3 EEPROM memory All the settings for ICp are stored in a non-volatile EEPROM. This memory is read on each start of the unit. Any changes made to the settings in Hägglunds ICp app are kept in the volatile memory of the ICp. It is recommended to save any changes to the EEPROM once the configuration is completed. Any changes not saved to EEPROM will be lost if the unit loses power. 2.4 Pump current control The pump current is monitored by ICp and kept in closed loop control to ensure that the current is accurate. There are separate settings for each pump solenoid to compensate for any differences. Adjustable dither settings ensure
