Notes:

1. Control equipment connected to the Associated Apparatus must not use or generate more than 250 Vrms or Vdc.

2. The IS Barriers or Equipment (Associated Apparatus) must be FM Approved and CSA Certified and the
configuration of Associated Apparatus must be FM Approved and CSA Certified under the Entity Concept. The
Associated Apparatus may be installed within the Hazardous (Classified) location for which it is certified. The
Associated Apparatus and hazardous location loop apparatus manufacturer’s control drawings must be followed
when installing this equipment. An AEx [ib] Associated Apparatus is suitable only for connection to Class I, Zone
1, Hazardous (Classified) Locations and is not suitable for Class I, Zone 0, or Class I, Division 1 Hazardous
(Classified) Locations.

3. Installation should be in accordance with ANSI/ISA RP12.6 “Installation of Instrinsically Safe Systems for
Hazardous (Classified) Locations” and Article 500 of the National Electrical Code (ANSI/NFPA 70).

4. The standard conduit is suitable for Type 4X installations. All others must be mounted in a suitable enclosure.

5. The standard conduit is suitable for Class I, II and III, Division 2, Groups A, B, C, D, F & G hazardous (classified)

locations. Dust-tight conduit seal must be used when installed in Class II and Class III environments.

The connection option “D” is suitable for Class I, Division 2, Groups A, B, C and D hazardous (classified) locations.

2.1.3 It is not necessary to remove the cover of the unit for calibration if the direct acting mode is desired.

2.2 Direct Acting Calibration

.2.1 In direct acting operation the unit is calibrated so that minimum input signal corresponds to minimum output

2.2.2 Apply the minimum input signal of the range being used (e.g. 4mA for a 4-20mA unit) (see figure 6).

2.2.3 Observe the output pressure. If necessary, adjust the zero screw until reaching minimum output pressure setting.

2.2.4 Apply the maximum input signal of the range being used (e.g. 20mA for a 4-20mA unit).

2.2.5 Observe the output pressure. If necessary, adjust the span screw until reaching maximum output pressure setting.

2.2.6 After setting the span it will be necessary to recheck the zero. Repeat steps 1-4 until both end points are at

2.3 Reverse Acting Calibration

2.3.1 When calibrated to operate in the reverse acting mode the minimum input signal produces the maximum output
pressure and increasing the input signal results in decreasing the output pressure. Setting the unit to operate in
the reverse acting mode is accomplished by positioning internal electrical switches.

CAUTION

2.3.2 Disconnect input signal and supply pressure. Take off the top cover by removing the four screws.

CAUTION

2.3.3 Position switches as illustrated in figure 8. Replace cover.

2.3.4 Set the input signal to the minimum valve being used. Turn the zero screw to set the maximum output pressure.

2.3.5 Set the span by applying the maximum input signal. Turn the span screw to set the minimum output pressure.

2.3.6 It may be necessary to repeat steps 2.3.4 – 2.3.5 until both end points are at desired values.
