The following table describes the attributes used by the Rotation Small modules:

Table 1. Rotation Small Attributes

Name

Type 1

Description

Default Value

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.
