1. Bleed Valves and Barbs: Bleeds gases out of gas supply lines. Calibration cup for sensor attaches here.
2. Controller: Bright blue digits on black back ground. Continuously displays current control gas level, control status, and alarm status in all chambers. Displays menu items and settings during programming.
3. Alarm: Will sound if Ambient gas monitor detects unsafe levels.
4. ZERO Calibration Gas Flowmeter: Used for calibration.
5. SPAN Calibration Gas Flowmeter: Used for calibration.
6. Needle Valves: Sets infusion rate of control gases in each chamber to accommodate different dynamics. Can manually override controller to shut off gas.
7. Accessory Receptacle: 10 Pin Receptacle is for connecting optional accessory units.
8. Communications Cable Jack: This cable relays information for the sensors.
9. Monitor Pod Umbilical: Flexible umbilical connects remote monitor pod to back panel. Semi-swivel connectors at both ends allow 360° orientation. Some models are hard welded; function is the same.
10. Alarm Receptacle: Connect an appropriate alarm to this jack.
11. RS 485 Connections: One cable attaches to a computer and the other cable attaches to another unit, to allow communication with the computer (if applicable).
12. Pump Connection: This 3 pin receptacle supplies power to the Mini Pod Pump.
13. Supply Gas Hose Barb: Barbs for 1/4 inch I.D. hose from gas sources. Handles pressure up to 40 PSIG.
14. Span Mix Barb: Barb for 1/4 inch I.D. hose from gas source.
15. Ground Stud: For grounding the unit to protect from electric damage.
16. Power Receptacle: 12VDC power supply connects here.
17. Monitor Pod Umbilical: Flexible umbilical connects remote monitor pod to back panel. Semi-swivel connectors at both ends allow 360° orientation. Some models are hard welded; function is the same.
