I. Functional specifications and parameters

Control panel display function LCD display, embedded installation mode, boot initialization time 3 seconds.

Wide working voltage range: DC18V ~ DC33V; High throwing load voltage: ≥DC110V; Wide operating temperature range: -20℃ ~ 80℃;

Resistance to transient pulse interference: ≥2000V (peak-to-peak).

Two, operation and setting steps

1. Self-locking function: to avoid misoperation, press the "setting" key, and then press the "" key twice continuously within 2 seconds to unlock the setting function;

2, the controller has three states: lubrication state, rest state, alarm state; In the case of no alarm, the lubrication state and the rest state cycle;

3. There are two kinds of lubrication conditions: manual lubrication and cyclic lubrication. Manual lubrication refers to the lubrication that is entered actively by pressing the manual button () for more than 3 seconds; Cyclic lubrication is the lubrication entered by the controller according to the program;

4, the working time is in 180 seconds after the pressure signal, and 30 seconds after the delay, automatically return to the rest state, working display backlight continues to light up for 20 seconds;

5, in the lubrication state, can display the lubrication state and lubrication time, lubrication time from "1" to accumulate when the pressure signal is detected (PS2 pressure switch display), continue to accumulate 30 seconds to stop; Time in seconds;

6, small current alarm (alarm display Err3) : enter the working state, start to detect the motor current, motor current is less than 0.15A alarm. Large current alarm (alarm display Err4) : 24V corresponds to 9A alarm, 7A does not alarm; 12V corresponds to 12A alarm,10A does not alarm.

7, 180 seconds timeout alarm: no pressure signal is detected within 180 seconds, the controller alarms, and Err1 is displayed. Fault and working times query function: in the resting state, the latest fault and cumulative working times can be queried;

8, the rest state display time mode (for example, 10:00), the rest time can be set, first press the "setting" key, then press the "" key twice to unlock, press" "" "to adjust; Setting range: 0.5-24 hours adjustable, increasing every 0.5 hours; And can store set values; The rest time is the countdown mode, the rest time power off memory: power on the first into the rest state, and the rest time according to the last time.

9. Sound and light warning are divided into 4 kinds:

①. The timeout alarm is displayed as Err1. ②. The open circuit alarm is displayed as Err3. 3. Large current alarm is displayed as Err4; (4) The oil shortage alarm is displayed as Err5 (SL-ECU22D has this function).

10, reset function: working state and alarm state press the "reset" key, forced to restore to the rest state;

11. Overvoltage protection circuit and transient suppression circuit: ensure that the whole machine does not burn out, failure and other phenomena when experiencing short-term overvoltage impact;

12, motor, signal each signal input circuit is set up isolation protection circuit to prevent the power line reverse connection; The power cord is connected backwards, and the monitor has no display.
