1.HANDLING PRECAUTIONS
IMPORTANT
For installation, wiring and maintenance in hazadous areas, please follow 1.5 Installation of Intrinsically Safe Type, 1.6 Installation of Flameproof Type and “Installation and Operating Precautions for TIIS Flameproof Equipment” at the end of this manual
The PK200 current-to-pneumatic converter is fully factory inspected before shipment. When the instrument is delivered, visually check the instrument and accessories to ensure that they are not damaged. This chapter describes the handling precautions, read them carefully before using the instrument.
For items other than those described in this chapter, see the relevant items.
If you wish to make inquiry, contact the distributor where you purchased the instrument or the nearest YOKOGAWA service station.
Figure 1.2 Data Plate for CSA Intrinsically Safe Type
Figure 1.3 Data Plate for FM Explosionproof Type
The data plate on the side face of the instrument base shows the model suffix code and specifications. With reference to the model suffix code and specifications in section 2.3, confirm that the instrument is as specified by the order.
For inquiry, inform us of the model suffix code and instrument serial number.
To prevent damage occurring during transportation, transport the converter in the original shipping container (box) with all packing items and equipment in its proper position.

(1) Select a storage place :
•Which is protected from rain and water.
•Which is free from vibration and impact.
•Whose temperature and humidity are as specified
below. Room temperature and humidity (approx. 25°C and 65%) are more recommendable.
Temperature: -10 to 60°C
Humidity: Less than 80%
(2)Store the converter in the packing condition of shipment from YOKOGAWA whenever possible.
To use the converter stably for a long time, determine an installation place, taking into account the following.
(1) Ambient Temperature
Avoid installing the instrument in a place subject to a large temperature gradient and variations. If the instrument is subject to plant-generated heat radiation, take measures such as provision of heat protection and good ventilation.
(2) Atmospheric Conditions
Avoid installing the converter in corrosive atmosphere. Should it be used in corrosive atmosphere, make provision for maintaining good ventilation.
(3) Magnetic Field
Please contact us in the case this instrument is installed the strong Magnetic Field.

•Option Code/L: Lightning Protector
Installed in the terminal box to protect internal circuitry from high voltage surges such as those caused by lightning induced.
•Option Code/AM: AUTO/MANUAL Switch Mounted on front of housing, in manual mode, output signal is varied by adjusting the external supply pressure regulator.
•Option Code/GW: Double Scale Pressure Gauge Double scales are kPa and kgf/cm2.
2. OVERVIEW
•Option Code/SS: Stainless Steal Screw and Bracket Screw and bracket, both are made of stainless steal.
•Option Code/RA: Reverse Action
Increasing of input signal to make output pressure decrease.
