Before disconnecting any cables to the EPC 400 it should be isolated by:
The EPC 400 only runs on 48 volts, it is not necessary to isolate.
Switching-off the EPC with the fuse switch, located in the top left hand corner of the box.
Switching-off the motor starter.
Switching-off the electrical supply to the EPC.
The EPC 400 controller is a sophisticated piece of microelectronics, which of the following statements best describes components and functions to be controlled?
Fail safe actions of valve actuation and motor stop facility.
Control of opening and closing water and the positioning of the interface for optimum separation.
Temperature control and correct positioning of the interface.
To monitor the transducer value and to take action if the level gets too high.
To keep a good check on the separator so the operator can sit in the control room and smoke.
The fuses on the front circuit board are numbered from the top as:
F1, F2 and F3.
F2, F3 and F1.
F3, F1 and F2.
F2, F1 and F3.
F3, F2 and F1.
What happens if you keep the alarm accept button pressed for more than 5 seconds?
It is possible to display extra process conditions.
32 previous alarms are displayed.
