OpERatING INStRUCtIONS (CONtINUED)

Normal Operation

Following the start-up procedure the operation of the dryer is fully automatic
and requires no further attention until shut down.
The green 'power on' LED and the green 'correct operation' LED should be
illuminated continuously.
The dryer contains two desiccant chambers, while one chamber is drying
the compressed air (adsorption), the other chamber is simultaneously
undergoing regeneration (desorption).
At a predetermined time both exhaust valves close and repressurization
begins. Every two and a half minutes the chambers are reversed in
function, this is the changeover point.
Changeover is characterised by an immediate venting of compressed air
from the chamber entering regeneration.
The dryer can be shut down at any point in its cycle and when restarted will
enter an automatic repressurization stage. After repressurization the cycle
will commence at the point at which it stopped. If power is switched on, the
dryer will enter an automatic repressurization stage at the point at which it
stopped.
Shut-Down procedure to Depressurize the Dryer
Prior to isolating the electrical supply close the outlet valve while
simultaneously opening the by-pass valve if fitted. Close the inlet valve.
The dryer will now be isolated from supply pressure. Cycle the dryer
for a minimum of 5 minutes to ensure the dryer vents and is completely
depressurized. When the dryer is completely depressurized, isolate the
electrical supply.
The by-pass valve should only be opened if the dryer is undergoing
maintenance.

alarm Signal

It is possible to get an alarm signal and control the dryer by a remote
control. In order to get the alarm and/or remote control the connector under
the dryer is to be used. Refer to the wiring diagram for wiring details.
