4.1Control Functions

4.1.1Analysis Section, fully explosion proof, Z or X purged Nema enclosure or Cenelec Purged (pending).

The control functions for the analysis section are located on the Front of the Enclosure module:

1.POWER ON/OFF: This function is hard wired into the enclosure for power to the control/analysis section.

2.a

X =	(C-A)(1000)
	(B-A)

For example, if the range of analysis is 20-80%, and a desirable alarm setpoint is 30%, then A = 20, B = 80, and C = 30

X =	(30-20)(1000)	= 167
	(80-20)
2.b RANGE:	Control unit allows changing the range by some

predetermined amount, such as 4X or 5X; i.e., triple range: low range of 0-100 ppm, mid of 250ppm and a high range of 0-500 ppm.

3.Mode: Programmable functions for incorporating an automatic zero, span or autoranging. Autocal also possible with fluids by valving or by filter solenoid.. Consult control unit sections of the manual.

4. Digital displayt: indicates the concentration of the component of interest. Consult control unit section for setting up units as ppm, mg/l, %, etc.
