Configuring Xl15C Start Stop Loops - Honeywell WebVision User Manual

Purpose
To configure logic loops.
Procedure
1. On the Configuration page click the Logic Loops tab.
The Logic Loops page appears on the right pane.
2. Select a logic loop from Select Loop.
3. Type a Loop Name. There are 32 Logic Loops. Default
name for the Logic Loops are Logc_Loop_1,
Logc_Loop_2, etc. The Logic Loop names can be
changed to make each Loop easier to identify. Select
the name to be changed in the Logic Loop name combo
and type the new name. A Logic Loop name can have a
maximum of 18 characters.
4. Select/Type the following options.
• ACDO: Analog Compare Digital Output - Compares
(<, >, or =) the values of 2 analog inputs and sets
the output to true or false. 3 ACDO buttons
(ACDO1,ACDO2,and ACDO3) are available in each
Logic Loop. Click an ACDO button to open the
ACDO Configuration dialog box.
• Analog Input 1 and 2: Select a Link Type and Link
Name for analog inputs.
• Analog Compare: This is used to compare the two
configured inputs. The logic usually is greater than,
less than, or equal to.
• Engineering Units: The measurement types are
listed here. When you select an Engineering Units
option, the corresponding Engineering unit appear
in the Sensor fields.
• Compare Deadband: The amount of difference
between the input values where the output state
does not switch.
• Output = ON when the condition is true (when
the condition between Input 1 and Input 2 is true)
• Output = OFF when the input 1 compared to
input 2 minus the deadband is false.
• On Delay Time: The delay in time for switching from
one state to another before the output value
switches to ON.
• Off Delay Time: The delay in time for switching
from one state to another before the output value
switches to OFF.
• AND: Logical AND function - If and only if all
configured digital input conditions (3 maximum) are
true, the output will be on. Three AND buttons
(AND1, AND2, and AND3) are available in each
Logic Loop. Click an AND button to open the And
Configuration dialog box.
• Digital Input 1, 2, and 3: Select a Link Type and
Link Name for digital inputs.
• On Delay Time: The delay in time for switching
from one state to another before the output value
switches to ON.
• Off Delay Time: The delay in time for switching
from one state to another before the output value
switches to OFF.
• OR: Logical OR function - If any one of the
configured digital input conditions (6 maximum) are
true, the output will be ON. OR must be configured if
the Logic Loop digital output is to be used. Click the
OR button to open the OR Configuration dialog
box.
• Digital Input (1 through 6): Select a Link Type
and Link Name for digital inputs.
• On Delay Time: The delay in time for switching
from one state to another before the output value
switches to ON.
• Off Delay Time: The delay in time for switching
from one state to another before the output value
switches to OFF.
• DCAO: Digital Compare Analog Output - Sets the
output value to equal analog input_1 if digital input is
true and analog input_2 if the digital input is false.
DCAO must be configured if the Logic Loop analog
output is to be used. Click the DCAO button to open
the DCAO Configuration dialog box.
• Digital Input: Select a Link Type and Link Name
for digital inputs.
• Analog Input 1 and 2: Select a Link Type and
Link Name for analog inputs.
• On Delay Time: The delay in time for switching
from one state to another before the output value
switches to ON.
• Off Delay Time: The delay in time for switching
from one state to another before the output value
switches to OFF.

Configuring XL15C Start Stop Loops

There are eight start/stop loops The start/stop control loops
direct control of loads based on time-of-day schedules. The
most common applications for start/stop control loops include
exhaust fans, pumps, lighting, or any other loads requiring
time-of-day control.
Purpose
To specify up to eight start/stop loops.
Mode
Configuration can be performed with the wizard Off-line or
On-line.
Procedure
1. On the Configuration page click Start Stop Loops.
The Start Stop Loop page appears on the right pane.
2. Select the required loop from Select Loop. There are
eight start/stop loops available. Select one to begin
configuring (SS_LOOP_1 through SS_LOOP_8).
3. Type the Loop Name. Loops are named SS_LOOP_1,
SS_LOOP_2, and so on. To change the name, type
over it and then click Change Name. Name the start/
stop loop according to the device being controlled. The
name can have a maximum of 18 characters.
4. Select the Link Type and Link Name for Bypass. The
bypass sensor (TOD) allows the user to place the Start/
Stop loop into occupied mode for a timed duration,
which depends on the Bypass Time value. The bypass
input changes the state to occupied. The bypass input
must remain true for the loop to remain in the bypass
state for the timed duration.
5. Select the Link Type and Link Name for Disable Loop.
This input is to control the Start/Stop loop. The disable
input disables the start/stop loop if the DI assigned to it
is ON and enables the loop if this DI assigned to it is
OFF. The Output is OFF when the loop is disabled.
6. Select the required Occupancy Override Period.
• Network_Wins: Equipment on/off times will follow
network schedule.
• Last_One_Wins follows the last override request.
