Releasing Applications Miscellaneous
The outputs are each set to a code appropriate for one of the three releasing phases: for example,
one code for the first alarm, a faster code when the Delay Timer activates, and a continuous tone
during releasing.
Program Program releasing zone ZR1 as follows:
ZR1 = Delay Time:15, Abort Switch:ULI, Cross Zone:YES, Soak Time:120
Map ZR1 to all inputs and outputs shown in this example.
Program logic zones as follows:
ZL1 = AND(OR(L1D1,L1D2,L1D3,L1D4,
L1D5,L1D6),NOT(L1M30))
When conditions are met for ZL1, a first alarm has occurred
in the releasing zone, but the
Delay Timer has not yet started. Map ZL1 to an output set to the code chosen for a first alarm
(L1M31 in this example).
ZL2 = AND(L1M30,NOT(L1M20))
When conditions are met for ZL2, the Delay Timer h
as started, but releasing has not begun.
Map ZL2 to the output set to the code chosen for when the Delay Timer activates (L1M32 in
this example).
ZL3 = OR(L1M20)
When conditions are met for ZL3, the 120
second releasing operation has begun. Map ZL3 to
the output that produces a continuous tone (L1M33 in this example).
Program output Type Codes as follows:
L1M20 = RELEASE CKT, L1M30 = INST RELEASE, L1M31 = CONTROL, L1M32 = CONTROL, L1M33 = CONTROL
