The inlet gas pressure should be regulated to pressures between 11
to 16 psig to maintain a flow between 0.5 to 1.0 SLPM. If pressure is too
low, the flow will drop below 0.5 SLPM at which the output of the
sensor is sensitive (see section 2.2.2). If pressure is too high, it will force
gas into the electrolyte and cause damage to the sensor. A pressure
regulator must be used if sample pressure varies farther than the
recommended range.
If greater sample flow is required for improved response time,
install a bypass in the sampling system upstream of the analyzer input.
EXHAUST OUT: Exhaust connections must be consistent with the
hazard level of the constituent gases. Check Local, State, and Federal
laws, and ensure that the exhaust stream vents to an appropriately
controlled area, if required
3.3.2 Electrical Connections
For safe connections, no uninsulated wiring should be able to come
in contact with fingers, tools or clothing during normal operation.
CAUTION: USE SHIELDED CABLES. ALSO, USE PLUGS THAT
PROVIDE EXCELLENT EMI/RFI PROTECTION. THE
PLUG CASE MUST BE CONNECTED TO THE CABLE
SHIELD, AND IT MUST BE TIGHTLY FASTENED TO
THE ANALYZER WITH ITS FASTENING SCREWS.
ULTIMATELY, IT IS THE INSTALLER WHO ENSURES
THAT THE CONNECTIONS PROVIDE ADEQUATE
EMI/RFI SIELDING.
3.3.2.1 P RIMARY I NPUT P OWER
The power cord receptacle and fuse block are located in the same
assembly. Insert the power cord into the power cord receptacle.
CAUTION: POWER IS APPLIED TO THE INSTRUMENT'S
CIRCUITRY AS LONG AS THE INSTRUMENT IS
CONNECTED TO THE POWER SOURCE. THE RED
SWITCH ON THE FRONT PANEL IS FOR SWITCHING
POWER ON OR OFF TO THE DISPLAYS AND
OUTPUTS ONLY.
The universal power supply requires 85–250 VAC, 47-63 Hz power
source.
