Series ITV1000/2000/3000/209 Precautions

Be sure to read before handling. Refer to back pages 1 and 2 for Safety Instructions,

“Handling Precautions for SMC Products” (M-E03-3) for Common Precautions.

Specific Product Precautions 6

Series ITV0000/1000/2000/3000

Handling

1. Connect the vacuum pump to the port, which is la-

beled “VAC”.

Pressure adjustment changes from “atmospheric

pressure to vacuum pressure” when the input sig-

nal is increased, and from “vacuum pressure to at-

mospheric pressure” when the input signal is de-

creased.

When adjusting the vacuum pressure, be careful not

to block the atmospheric pressure inlet port labeled

“ATM”.

Since this product is designed exclusively for use

with negative pressure, be careful not to apply posi-

tive 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 practi-

cal to change the vacuum pump, install a capacity

tank (volume depending on the operating condi-

tions) on the VAC side.

6. The vacuum pressure response time after a change

in the input signal is influenced by the internal volu-

me 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.

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 pres-

sure will be held only temporarily and is not guaran-

teed. In addition, when atmospheric pressure is de-

sired, shut off the power after reducing the set pres-

sure, and then introduce atmospheric pressure by

using a vacuum release valve, etc.

If the power for this product is cut off by a power

failure, etc. when it is in a controlled state, the set-

ting 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.

If the VAC side pressure to this product is interrup-

ted 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 re-

leased from this product in the range below –1.3

kPa. In cases where the pressure needs to be redu-

ced completely to 0 kPa, install a 3 port valve, etc.

on the setting side to discharge the residual pressu-

re.

11.

This product is adjusted for each specification at the

factory before shipment. Avoid careless disas

sembly or removal of parts, as this can cause failu

re.

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 wi-

res, as this can cause malfunction.

13.

Use caution that the right angle cable does not rota-

te 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) For avoiding the influence of noise or static electricity, install

this product and its wiring as far as possible from strong

electric fields such as those of motors and power lines, etc.

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.
