Configuration

Pressure parameters

Low Pressure Alarm Level: The pressure at which Low Pressure will announce an alarm condition. The Low Pressure Alarm must be lower than the Minimum Low Pressure.

The factory default is 0.15 psig (10 mbar).

Low Limit Pressure: The low set point of the operating pressure range for the dehydrator. This is the pressure at which the unit will turn off the compressor during compressor operation. The Low Limit Pressure must be less that the High Limit Target Pressure by at least 0.1 psig (7 mbar).

The factory default Low Limit Pressure is 0.30 psig (21 mbar).

High Limit Target Pressure: The high set point of the operating pressure range for the dehydrator. This is the pressure the unit will target during compressor operation. The actual turn off pressure is adjusted in software every pressurization cycle after determing the rate of pressure change during that cycle.

This software compensation for rate of pressure change during pressurization minimizes compressor undershoot. High Limit Target Pressure must be between 0.20 psig and 7.5 psig (14 mbar and 517 mbar).

The factory default High Limit Target Pressure is 0.50 psig (34.5 mbar).

High Pressure Alarm Level: The pressure at which High Pressure will announce an alarm condition. The High Pressure Alarm must be higher than the Maximum Pressure.

The factory default is 1.5 psig (103.5 mbar).

The pressure unit displayed by the ADH NETCOM is configurable as either psig or mbar.

The factory default is psig.

Small System: A small system is a low volume system that causes the dehydrator to have a low duty cyle with frequent but short pumping cycles. Selecting to run configured as a small system will engage the offline air drying canister as a accumulation reservoir as long as that canister is not in a regeneration cycle. Another feature of a small system is that the pump will ramp up air flow slower.

Configuring a dehydrator as a small system will increase the reported duty cycle while decreasing how often the pump cycles.

Serial Port Configuration

The ADH NETCOM has three serial ports.

  • Unused: Default.
  • SA Slave: Selected if the port is being used by a dehydrator to connect to another dehydratr which is configured as a master. The master dehydrator will control both units.
  • ASCII: Select if connecting to a termianl and desire plain text status.
  • SA Master: Select if the port is being used by a dehydrator to connect to another dehydrator in order to control both dehydrators from this dehydrator.

Select to operate at 1200 baud rather than the normal 9600 baud.

Select to enable pullups on this port.
