The multi-function input terminals can be used to monitor external fault contacts. When

the External Fault 1-4 signals are inputted,

EF5

EF8

are displayed on the Digital

Operator (steady for a major fault situation, blinking for a minor fault situation). The

second digit of the Sn-15 thru Sn-18 setting is entered as a hexadecimal value; when

converted to its binary equivalent, it defines what type of external fault contact is used and

how the GPD 503 will react to the fault input.

Binary — 0 0 0 0

0 = N.O. contact

1 = N.C. contact

0 = always detected

1 = during operation

00 = ramp to stop

01 = coast to stop

10 = emergency stop

11 = continue operation

(minor fault)

EXAMPLE:

To program External Fault 1 (terminal 5)

for a N.C. contact, always detected, and

GPD 503 to continue operation, solve

for X:

Sn-15 data =

X = 1 1 0 1

N.C. contact

always detected

continue operation

= 1 1 0 1 (binary) = D (hex)

For the same type of input at External Fault 2 (terminal 6):
