for this part to be TRUE
When this is TRUE
Then all outputs programmed with this equation will be turned ON.
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.
