Measures regarding power supply sequence (start up sequence)
•
To ensure and ease the power supply sequence of the expansion FP0 adapter, supply the power for
the expansion FP0 adapter from the servicing power supply for the input of the FP-X control unit.
•
The power supply sequence should be set up so that power to the FP0 expansion unit is turned on
before the FP-X system power supply.
•
The power supply sequence should be set up so that power to the FP-X system and FP0 expansion
unit is turned off before the input/output power supplies. If the input/output power supplies are turned
off before the power to the expansion FP0 adapter, the control unit will detect the input fluctuations and
may begin an unscheduled operation.
When turning on:
Power supply for FP0
→
Power supply for FP-X, Expansion FP0 adapter
→
Power supplies for I/O
devices
When turning off:
Power supply for FP-X, Expansion FP0 adapter
→
Power supply for FP0
→
Power supplies for I/O
devices
Grounding
- In situations of excess noise
Under normal conditions, the inherent noise resistance is sufficient. However, in situations of excess
noise, ground the instrument to increase noise suppression.
- Exclusive grounding
•
The grounding connection should have a resistance of less than 100
Ω
.
•
The point of grounding should be as close to the PLC unit as possible. The ground wire should be as
short as possible.
•
If two devices share a single ground point, it may produce an adverse effect. Always use an exclusive
ground for each device.
Note:
Depending on the surroundings in which the equipment is used, grounding may cause problems.
[Example]
Since the power supply line of the expansion FP0 adapter power supply connector is connected to the
function earth through a varistor, if there is an irregular potential between the power supply line and earth,
the varistor may be shorted.
