| number | trouble | Blink frequency (1 times/sec.) | interval time (sec.) | |
| 1 | emergency stop | On and no blinking | no | check whether emergency stop button pop-up |
| 2 | motor overload | 1 | 3 | press the reset button on the contactor |
| 3 | the pressure of inlet water to the pump is low | 3 | 3 | check input water pressure sensor when the pressure is more than 40 |
| 4 | oil cylinder piston runs over clocked (shifting too fast) | blink at 1 times/sec. | no | leaking water/bad orifice/intensifier is losing pressure |
Check whether the white light work or not:
Turn on the pump with no high pressure, turn off the inlet water, the white light is flashing 3 times continuously every 3 second. If it is not flashing then it is the light issue.
There are 4 kinds of alarm will make the pump stop and the white light blink or solid on.
1. Emergency stop
There are two emergency buttons
2. Intensifier over load
For 50,000PSI, 0.012 inch orifice, it usually cycles 66 times in one minute. Some thing is bad causing it cycling too fast.
3. Water pressure too low.
water pressure must be above 40 PSI. This sensor is linked to the PLC via the line 0100. Picture attached. This signal can be bypass through disconnecting line 0100.
4. Electrical current over load
This one is linked to PLC via the line 0010. Picture attached. This signal can be bypass through connecting 0010 and 225 together.
