5.3 Start-up and shut down
ACT ES 200-500 3phase - For short periods of inactivity, (max 2-3 days) we recommend that
power is maintained to the dryer and the control panel. Otherwise, before re-starting the
dryer, it is necessary to wait at least 2 hours for the compressor crankcase heater to heat
the oil of the compressor.
Start-up (refer to paragraph 7.1 Control Panel)

Check the condenser for cleanliness.

Turn ON the switch - pos. 1 on the control panel.

Ensure that electronic instrument is ON.

If the temperature displayed on the electronic instrument is sufficiently high, verify that the refrigerating
compressor starts within a few minutes. NOTE! – With low temperatures, the refrigerating compressor
will remain OFF.

Wait a few minutes; verify that the DewPoint temperature displayed on electronic instrument is correct
and that the condensate is regularly drained.

Switch on the air compressor.
Shut down (refer to paragraph 7.1 Control Panel)

Check that the DewPoint temperature indicated on the electronic instrument is within range.

Shut down the air compressor.

After a few minutes, turn OFF the switch - pos. 1 on the control panel.
ACT ES 200-500 3phase - Dryer remote control ON-OFF

Remove jump on terminals 1 and 2 of the terminal strip and wire a dry contact – potential free (see
electric diagram).

Turn ON the switch - pos. 1 on the control panel.

Close contact on terminal 1 and 2 switch ON the dryer

Open contact on terminal 1 and 2 switch OFF the dryer
Use dry contacts only (potential free) suitable for 230 Vac. Assure an adequate isolation of
potentially dangerous powered parts.
NOTE : A DewPoint within 32°F (0°C) e +50°F (+10°C) displayed on electronic instrument is correct
according to the possible working conditions (flow-rate, temperature of the incoming air, ambient
temperature, etc.).
In the ECO operating mode (Energy Saving, ESS=YES – see section 7.12.7), the refigerating compressor is
switched ON and OFF by the electronic instrument, according to thermal load applied to the dryer. The dryer
must remain ON during the full usage period of the compressed air, even if the air compressor works
intermittently.
The number of starts/stops by pressing the ON-OFF switch - pos. 1 of control panel should
be limited to 6 per hour
.
The dryer must stop running for at least 5 minutes before being started up again.
Frequent starts may cause irreparable damage.
The user is responsible for compliance with these rules.
