E.2.3 Trouble Equations
A trouble equation follows the same syntax rules as the logic equation. The system allows up to a
hundred trouble equations, ZT001 through ZT100. It differs from a logic equation in the following
manner:
•
Equations evaluate as true when the arguments go into trouble.
•
Argument entries may consist of system trouble codes. Refer to Appendix H, “System
Troubles” for a listing of these codes.
Examples:
AND(L1M149,L2M110) will evaluate as true when both arguments go into trouble.
OR(ZT049,ZT050) will evaluate as true when either argument goes into trouble.
These
have to be
ON
These have
to be ON … and this OFF
Any TWO of
these have to be
ON
for this part to be TRUE
for this part to be TRUE
for this part to be TRUE
When this is TRUE OR When this is TRUE OR When this is TRUE
Then all outputs programmed with this equation will be turned ON.
