D.4.5 Time Delay Functions
The "DEL" Operator
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.
The "SDEL" Operator
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 too few parentheses, too
many or too few arguments inside the parentheses, unknown function and unknown device type.
D.5 CBE Example
An example of CBE, where monitor module 1M101 lists zone Z04 and Z05, and control module
1M108 lists zone Z05 and zone Z07:
P R O G R A M M O N I T O R
When monitor module 1M101 activates, the following CBE takes place:
1. Software Zones Z04 and Z05 activate.
2. Since control module 1M108 has Z05 in its CBE list, all of its outputs would activate. All
output devices with Z04 or Z05 would activate.
