Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 
Mark 1, 3 and 4 Position Indicating Switch Model .....IS is an assembly, used in conjunction with a valve, damper and/or actuator to which it is mechanically or magnetically linked.
The switches provide a visual and an electrical output corresponding to the position of a valve, damper and/or actuator.

The electrical signals are, depending on the version, provided by a potentiometer, a 4 - 20 mA current transmitter (with or without HART communication), proximity sensors (Namur) or switch contacts.

Ambient temperature range:
-25 °C to +40 °C for switches type D and I
-40 °C to +40 °C for switches type O, R, S, V and W
-50 °C to +40 °C for switches type A, G and H

Electrical data

Potentiometer circuit
Supply and output (terminals 1 and 3 and 2 and 3 respectively):
in type of protection intrinsic safety Ex ia IIC, only for connection to a certified intrinsically safe circuit, with following maximum values:
Ui = 30 V; Ii = 50 mA; Pi = 0.65 W; Ci = 0 nF; Li = 0 mH.

Transmitter circuit (with or without HART communication)
Supply and output (terminals + and -):
in type of protection intrinsic safety Ex ia IIC, only for connection to a certified intrinsically safe circuit, with following maximum values:
Ui = 30 V; Ii = 100 mA; Pi = 1.3 W; Ci = 4 nF (Ci = 0 nF for the transmitter without HART communication); Li = 0 mH.

Sensor circuit (Namur)
Supply and output (terminals + and -):
in type of protection intrinsic safety Ex ia IIC, only for connection to certified intrinsically safe circuits, with following maximum values per sensor circuit:
Ui = 16 V; Ii = 76 mA; Pi = 0.242 W; Ci = 40 nF; Li = 50 µH. 

Switch circuit (contacts)
Supply and output (terminals C, NC and NO):
in type of protection intrinsic safety Ex ia IIC, only for connection to certified intrinsically safe circuits, with following maximum values per switch circuit:
Ui = 30 V; Ii = 100 mA; Pi = 1.3 W; Ci = 0 nF; Li = 0 mH.
 
CONDITIONS OF CERTIFICATION: YES as shown below:
 
Because the enclosure of the Position Indicating Switch is made of aluminium, if it is mounted in an area where the use of equipment protection level Ga is required, it must be installed such that, even in the event of rare incidents, ignition sources due to impact and friction sparks are excluded.
