19) Product Coding for Fault Resistor and Customer EOL Resistor 
 

The customer is able to identify the resistor values chosen on purchase from the product code. This is represented by the last two 
characters: 
 

GNExB2X05DC024AS1S1R/A-

AFZ

 

 

•

 

The first A character denotes the value of the Fault Resistor (FR). Default value is 2.2K Ohm (Code = A) unless an 
alternative value is requested when ordering. 

•

 

The second F character denotes the value of the Current Sense Resistor (CSR). Default value is 3.3K Ohm (Code = F) 
unless an alternative value is requested when ordering. 

•

 

The third Z character denotes the value of the unit End Of Line Resistor (EOL). By default no EOL resistor is factory fitted 
(Code = Z). A factory fitted EOL resistor can be specified when ordering. 

 
The values of resistors available are shown in table 6 below. 
 

Code 

Resistor Value 

 

 
 
Default resistor coding is as follows: 
 

GNExB2X05DC024AS1S1R/A-

AFZ

 

 
Example of a custom requirement resistor coding: 
 

GNExB2X05DC024AS1S1R/A-

GEF

 

 
Where the 

(FR) Fault Resistor is (G = 3.9 kΩ)

 

(CSR) Current Sense Resistor is (E = 2.7 kΩ)

 

(EOL) End Of Line resistor is (F = 3.3 kΩ)

 

A 

2.2 kΩ

 

 

B 

1.0 kΩ

 

 

C 

1.5 kΩ

 

 

D 

1.8 kΩ

 

 

E 

2.7 kΩ

 

 

F 

3.3 kΩ

 

 

G 

3.9 kΩ

 

 

H 

4.7 

kΩ

 

 

J 

5.6 kΩ

 

 

K 

6.8 kΩ

 

 

L 

8.2 kΩ

 

 

M 

11 kΩ

 

 

Z 

None Fitted 

 

 

Note

: To utilise the full monitoring functionality the 4-wire configuration is recommended. An EOL resistor is not required for this 

configuration. 
 
The alternative 2-wire configuration requires an EOL resistor to be fitted. The EOL resistor can be specified during ordering and 
factory fitted or selected and fitted during the beacon installation. 
 
See section 9 for EOL resistor location and wattage requirements. E2S recommends a value of 2.2K Ohm. If an alternative value is 
required, please see section 15-2. 
 
Both the (FR) Fault Resistor and (CSR) Current Sense Resistor are factory fitted and cannot be user replaced.
