Installing the 500S Controller
Locate the ideal location for the 500S controller. Brackets can be supplied to mount the controller on the Chart
prefabricated support stand or 1½”diameter rod or round bar
. If Chart’s prefabricated brackets are not utilized, the
controller’s mounting tabs can be utilized.
The front of the 500S controller (image below) displays the system status.
The gauge assembly on the top of the 500S controller provides the
following information:
Dosing Head Pressure
The dosing head pressure gauge measures the head pressure of the
liquid nitrogen in the reservoir and acts as a liquid level indicator.
The pressure gauge should read between 0.4 – 0.5 psi when the
reservoir is full.
Gas Regulator Pressure (preset to 60psi)
The regulator controls the pressure of the gaseous nitrogen to the
dosing head valve. If necessary, on-site adjustments can be made.
Only gaseous nitrogen should be used in this application. Air,
even if it is dry compressed air, should NEVER be used as an
alternative.
Source Pressure
This gauge measures the pressure of the liquid nitrogen source.
This pressure reading should read between 3-22psi depending on
the source of liquid nitrogen (house system or Dura-Cyl
®
Liquid
Cylinder fed).
