GSDA-AI-A8 Terminal Block Description

Terminal Block Descriptions

Terminal

Description

P3 Terminal Blocks

P3-1

(- 4-20 mA Input) – Connect this terminal to the next 4-20 mA device in the loop, 

or, if the GSDA-AI-A8 is the last device in the current loop, then connect this 

terminal to the  - (negative) side of the current loop�

P3-2

(+ 4-20 mA Input) –Connect this terminal to the previous 4-20 mA device in the 

loop, or, if the GSDA-AI-A8 is the first device in the current loop, then connect 

this terminal to the  + (positive) side of the current loop�

P3-3

(- 4-20 mA Output) – Connect this terminal to the next 4-20 mA device in the 

loop, or, if the GSDA-AI-A8 is the last device in the current loop, then connect 

this terminal to the  - (negative) side of the current loop�

P3-4

(+ 4-20 mA Output) –Connect this terminal to the previous 4-20 mA device 

in the loop, or, if the GSDA-AI-A8 is the first device in the current loop, then 

connect this terminal to the  + (positive) side of the current loop�

P3-5

(S1 Input) – Connect this terminal to one side of a SPST switch to control Auto/

Manual Operation� If switch is OPEN (or unconnected), MD40/50-420 Target 

Speed will come from its Target Speed setting (as usual), if the switch is CLOSED, 

MD40/50-420 Target Speed will follow the GSDA-AI-A8 4-20 mA Current Loop 

Input� This signal is internally “pulled-up” via a 15K Ohm resistor�

P3-6

(COM) – This is the common point for the control logic� Normally, the other side 

of the SPST Auto/Manual switch would be connected to this terminal�

P6 Terminal Blocks

P6-1

(NC) – This is the normally-closed contact of the user-assignable GSDA-AI-A8 

Alarm 2 relay�

P6-2

NO) – This is the normally-open contact of the user-assignable GSDA-AI-A8 

Alarm 2 relay�

P6-3

(C) – This is the common contact of the user-assignable GSDA-AI-A8 Alarm 2 

relay�

NOTE:  P3-1, 2, 3, & 4 are isolated inputs.

How to Change a Parameter’s Value

1)  Hold down the Enter button until Parameter Mode is entered. The ‘Parm’ indicator will light up
2)  Using the Up and Down buttons, select the desired parameter number to view or edit
3)  Press the Enter button to change the value of the parameter. The ‘Valu’ indicator will light up
4)  Using the Up and Down buttons, change the parameter’s value as desired
5)  Press the Enter button to save the changes (Returns to Parameter Mode)
6)  Select Parameter Zero (“0”) and press the Enter button to return to Running Mode

NOTE:  See control manual for further explanation
