Rotation Small Common Attributes |
|||
BLRROTATE-STATE, CHROTATE-STATE, CWPROTATE-STATE, PCHWPROTATE-OUTSTATE, PHWPROTATE-STATE, SHWPROTATE-OUTSTATE, SCHWPROTATE-OUTSTATE, or CTROTATE-STATE (Operating State) |
G |
Identifies the operational state of the sequencer at any given point in time. |
Idle |
BLR-RUNNING, CH-RUNNING, CWP-RUNNING, PCHWP-RUNNING, PHWP-RUNNING, SHWP-RUNNING, SCHWP-RUNNING, or CT-RUNNING (Current Stage) |
V |
Indicates the number of active outputs of the sequencer. |
0 |
Device X Enable |
Establishes the enable status of the sequencer device outputs. A value of FALSE takes the associated device out of service. Only the enables for the number of outputs are shown. This module is created with X individual Device X Enable inputs based on the Number of Outputs. |
True |
|
Device X Out |
SC |
Contains the output value for the corresponding device. This module is created with X individual Device X Output inputs based on Number of Outputs. |
False |
Device X Rank |
Represents the ranking of each device. This value establishes the order by which the device outputs are activated. Only the ranks for the number of outputs are shown. This module is created with X individual Device X Rank inputs based on Number of Outputs. |
0.0 Units: % |
|
Input |
Provides a floating value control signal input to this module. This input is compared against the make and break limits to determine how many outputs to activate. |
0.0 Min Value: 0.0 Units: % |
|
Instant Shutdown |
Forces all outputs inactive when TRUE. When FALSE, the module monitors the input and stages the outputs. When this value transitions from FALSE to TRUE, all of the outputs are deactivated instantly (ignoring any Minimum On Timers and the Interstage Off Timer). |
False |
|
Interstage Off Delay Time |
Defines the minimum time interval that must elapse between the sequential deactivation of multiple Sequencer stages unless the Instant Shutdown value is TRUE or the module is disabled. |
0 Seconds |
|
Interstage On Delay Time |
Defines the minimum time interval that must elapse between the sequential activation of multiple Sequencer stages. |
0 Seconds |
|
Interstage Timing |
SC |
Provides an indication of when an interstage timer is active. |
False |
Min Off Time |
Indicates the minimum time that an output must remain off before it can be reactivated to an on condition following deactivation. A separate timer is established for each device output upon deactivation. Until the time interval expires, the output is blocked from being reactivated unless Rotate Now has transitioned from FALSE to TRUE. |
600 Seconds |
|
Min On Time |
Indicates the minimum time interval that an output must remain on before it can be deactivated to an off condition following activation. A separate timer is established for each device output upon activation. Until the time interval expires, the output is blocked from being deactivated unless the Instant Shutdown value is TRUE, the module is disabled, or Rotate Now has transitioned from FALSE to TRUE. |
600 Seconds |
|
Rotate Now |
Provides rising edge activation. This attribute retains a value of TRUE until it is written back to FALSE. Writing this attribute to TRUE causes an immediate rotation based on the current ranks. |
False |
|
Boiler Rotation Small and Chiller Rotation Small Attributes |
|||
Min On Time |
Indicates the minimum time interval that an output must remain on before it can be deactivated to an off condition following activation. A separate timer is established for each device output upon activation. Until the time interval expires, the output is blocked from being deactivated unless the Instant Shutdown value is TRUE, the module is disabled, or Rotate Now has transitioned from FALSE to TRUE. |
30 Seconds |
|
CW Pump Rotation Small, Primary CHW Pump Rotation Small, Primary Pump Rotation Small, Secondary Hot Water Pump Rotation Small, Secondary CHW Pump Rotation Small, and Tower Rotation Small Attributes |
|||
Min Off Time |
Indicates the minimum time that an output must remain off before it can be reactivated to an on condition following deactivation. A separate timer is established for each device output upon deactivation. Until the time interval expires, the output is blocked from being reactivated unless Rotate Now has transitioned from FALSE to TRUE. |
30 Seconds |
|
Min On Time |
Indicates the minimum time interval that an output must remain on before it can be deactivated to an off condition following activation. A separate timer is established for each device output upon activation. Until the time interval expires, the output is blocked from being deactivated unless the Instant Shutdown value is TRUE, the module is disabled, or Rotate Now has transitioned from FALSE to TRUE. |
