devices listed below:
Equations must be evaluated before use in another equation.

7KH ´'(/µ 2
HUDWRU
Used for delayed operation
Example: DEL(HH.MM.SS HH.MM.SS (ZE5))
• The first HH.MM.SS is the delay time, the second HH.MM.SS is the duration time.
• If delay of zero is entered (00.00.00), the equation will evaluate true as soon as the
internal equation (ZE5) evaluates true and will remain that way for the specified
duration, unless the internal equation becomes false.
• If no duration is specified, then the device will not be deactivated until a reset
occurs or the internal equation evaluates false.
7KH ´6'(/µ 2
HUDWRU
A latched version of the DEL operator. Once the equation evaluates true, it remains
activated until a reset, even if the internal equation (ZE5) becomes false.
Example: SDEL(HH.MM.SS HH.MM.SS (ZE5))
• The first HH.MM.SS is the delay time, the second HH.MM.SS is the duration time.
• If delay of zero is entered (00.00.00), the equation will evaluate true as soon as the
internal equation (ZE5) evaluates true and will remain that way for the specified
duration.
• If no duration is specified, then the device will not deactivate until reset.
The installer can enter the equations in any combination wanted as long as the format of
the logic function or time delay is followed from the lists above. Error checking will be
performed after the user has entered the complete equation. Possible errors are too
many or two few parentheses, too many or two few arguments inside the parentheses,
unknown function and unknown device type.
