1. Overview

HRDK-03B dry oil electrical control box is a control system with CPU as the core. There are digital displays and touch keys on the control box panel. The lubrication time and interval can be displayed and set on the panel, and all controls can be completed on the panel. .

Automatically identify the signals of the differential pressure switch, pressure controller and hydraulic reversing travel switch, take the variable of the signal as the reversing mark, and adopt a two-wire wiring methodProcess lubrication, the wiring does not need to be oriented, and the dual commutation method of pressure signal and time signal is used to ensure reliable commutation of the system.

The HRDK-03B electric control box can replace all old-fashioned dry oil electric control boxes. It is a relatively advanced and scientific electrical control box for dry oil lubrication systems.

The HRDK-03B electric control box can operate automatically, manually control, remotely start and stop, as well as automatically control the fuel pump and DCS signals (fuel pump operation, system failure, ready).

4. Key points for using the new single-chip microcomputer multi-functional electrical control box

1. This model of electrical control box is compatible with all old models in the table;

2. Do not connect peripheral components that are not in the configuration table;

3. Compatible with differential pressure switch, pressure switch, hydraulic reversing valve, and can be connected into a two-wire system;

4. Do not set the lubrication monitoring time too long. It should be 1 to 3 minutes longer than the actual oil supply time, otherwise the scheduled reversal time will be too long;

5. The lubrication monitoring time and interval must be set before operation;

6. The remote control is a passive contact (active access will burn the control box).

Notice:

After power on, the monitoring time and interval time are alternately displayed.

The corresponding digital tube flashes when the "monitoring time" or "interval time" key is pressed.

The setting bit moves one bit each time the key is pressed, and the time can be set cyclically for the flashing bits.

The maximum interval time is 9999 hours on one screen, 00 minutes and 59 seconds on the second screen, and the maximum lubrication time is 99 minutes and 59 seconds.

After setting the time, you must press the "Reset" button to confirm before proceeding to the next step.

Press the "Reset" button to stop any operation and return to standby mode

If the overload indicator light is on, the system will shut down and the thermal relay can be reset before normal operation.
