Straight type
Cable
connector
Right angle type
Be sure to read before handling. Refer to pages 14-21-3 to 14-21-4 for Safety Instructions and Common
Precautions.
Caution
1. Connect the vacuum pump to the port, which is labeled "VAC".
2. Pressure adjustment changes from "atmospheric pressure to
vacuum pressure" when the input signal is increased, and
from "vacuum pressure to atmospheric pressure" when the
input signal is decreased.
3. When adjusting the vacuum pressure, be careful not to block
the atmospheric pressure inlet port labeled "ATM".
4. Since this product is designed exclusively for use with negative
pressure, be careful not to apply positive pressure in error.
5. In cases where the vacuum pump being used has a relatively
small capacity, or the piping has a small inside diameter, etc.,
large variations in the set pressure (the range of pressure
variation when changing from no flow to flow state) may
appear. In this situation, the vacuum pump or the piping, etc.
should be changed. In cases where it is not practical to
change the vacuum pump, install a capacity tank (volume
depending on the operating conditions) on the VAC side.
6. The vacuum pressure response time after a change in the
input signal is influenced by the internal volume on the setting
side (including piping). Since the capacity of the vacuum pump
also influences the response time, give careful consideration
to these points before operation.
7. If the electric power is shut off when in a control state, the
pressure on the setting side will go into a holding condition.
However, this setting side pressure will be held only
temporarily and is not guaranteed. In addition, when
atmospheric pressure is desired, shut off the power after
reducing the set pressure, and then introduce atmospheric
pressure by using a vacuum release valve, etc.
8. If the power for this product is cut off by a power failure, etc.
when it is in a controlled state, the setting side pressure will be
held temporarily. Further, if operated without sealing the
setting side so that atmospheric air is sucked in, handle with
care as air will continue to be sucked in.

Handling
9. If the VAC side pressure to this product is interrupted while
the power is still on, the internal solenoid valve will continue
to operate and may cause a humming noise. Since this may
shorten the life of the product, be sure to shut off the power
when the VAC side pressure is shut off.
10. The setting side pressure cannot be completely released
from this product in the range below –1.3 kPa. In cases
where the pressure needs to be reduced completely to 0 kPa,
install a 3 port valve, etc. on the setting side to discharge the
residual pressure.
11. This product is adjusted for each specification at the factory
before shipment. Avoid careless disassembly or removal of
parts, as this can cause failure.
12. The optional cable connector is a 4-wire type. When the
monitor output (analog output, switch output) is not being
used, keep it from touching the other wires, as this can cause
malfunction.
13. Use caution that the right angle cable does not rotate and is
limited to only one entry direction.
14. Take the following steps to avoid malfunction due to noise.
1) Eliminate power supply noise during operation by
installing a line filter, etc. in the AC power line.
2) Install this product so that it will not be effected by noise,
keeping the product and its wiring away from strong
electric field sources such as motors and power lines.
3) Make sure to take protective measures against load surge
for an induction load (solenoid valves, relays, etc.).
15. Refer to the instruction manual included with the product for
details on its handling.
