i2P-100 Transducer July 2014 Instruction Manual D103198X012 CAUTION Dropping or rough handling of the transducer can cause damage to the converter module resulting in a shifted output or a minimum output. Description The transducer receives a 4‐20 mA DC input signal and transmits a proportional user field‐configurable pneumatic output pressure to a final control element. The pneumatic output range are typically 0.2 to 1.0 bar (3 to 15 psig), 0.4 to 2.0 bar (6 to 30 psig), and 0.14 to 2.

Instruction Manual i2P-100 Transducer D103198X012 July 2014 Mounting When a transducer is ordered as part of a control valve assembly, the factory mounts the transducer on the actuator and connects the necessary tubing, then adjusts the transducer as specified on the order. See figures 3 and 4 for typical mounting configurations. Figure 3. Fisher i2P‐100 Electro‐Pneumatic Transducer Mounted on a Size 30 667 Sliding‐Stem Actuator Figure 4.

i2P-100 Transducer July 2014 Instruction Manual D103198X012 Note If the i2P‐100 transducer is used in a valve assembly with a positioner, no hook‐up for diagnostic testing is required for the i2P‐100. The hook‐up for diagnostic testing should be installed at the positioner. Install the connectors and hardware between the i2P‐100 transducer and the actuator. 1. Before assembling the pipe nipple, pipe tee, pipe bushings, actuator piping, and connector body, apply sealant to all threads. 2.
PAGE 15
Instruction Manual i2P-100 Transducer D103198X012 July 2014 WARNING Select wiring and/or cable glands that are rated for the environment of use (such as hazardous location, ingress protection, and temperature). Failure to use properly rated wiring and/or cable glands can result in personal injury or property damage from fire or explosion. Wiring connections must be in accordance with local, regional, and national codes for any given hazardous area approval.
PAGE 16
Instruction Manual i2P-100 Transducer D103198X012 July 2014 For intrinsically safe areas, current monitoring during operation must be with a meter approved for use in hazardous areas. Equipment Required Choose a current or voltage source that is capable, without switching ranges, of driving the transducer through its entire input range. Switching ranges on a current or voltage source will produce spikes or mid‐scale reverses in the input signal presented to the transducer, causing errors.

Instruction Manual D103198X012 i2P-100 Transducer July 2014 1. Remove electronics module cover (cover adjacent to conduit entry, see figure 3 and 4). CAUTION Do not attempt to remove either of the housing caps if the locking set screws (key 8) are engaged. Removing housing caps without disengaging the set screws can cause damage to the housing caps. 2. Input and output ranges are selectable by dip switch selection. Refer to figure 10 for dip switch settings.

If not, ensure the dripwell is not plugged because of excessive moisture accumulation. If necessary, drain off any moisture, and clean or replace the filter element. 4. Force the converter module to maximum output pressure with a 30 mA DC signal. Output pressure should build up to the approximate value of the supply pressure [maximum of 3.4 bar (50 psi)]. 5.
