1 Specifications
The Rack Monitor 8800E/8801E is a loading rack monitoring system detects and communicates an overfill
condition to the loading rack control automation equipment by means of a normally open relay contact. In
addition this non-permissive condition as well as diagnostic information is displayed. A typical system
contains loading rack control monitor (88xxE Rack Monitor) and a API 10 wire screened coiled cable with a
black 10 pins 4 J-slot plug (Model 7400E).
Thermistor and optic signal inputs allow compatibility with the NEN-EN13922 and two other API standard
signaling conventions commonly used in the industry. Either of these signals comes from the truck/trailer
mounted on-board control monitor or sensors. The 88xxE rack monitor supersedes the 84xx and 85xx type
rack monitors and are suitable for hazardous locations with intrinsically safe outputs, and are housed in a IP
65, Explosion Proof “d” Enclosure.
There are two versions available. The Rack Monitor 8800E is a complete version with display. The Rack
Monitor 8801E is a version without a display. The installation of both versions is the same.
