Descriptor

Description

 

 

 

01

CTLR ADDRESS

Identifies the controller on the FLN trunk. Valid values: 0 through 98.

 

 

 

02

APPLICATION

The identification number of the Application running in the controller.

 

 

 

05

LOW ALM

This point displays an ON or OFF status. When the exhaust flow goes below the

 

 

value specified at LOW ALM LMT for the time specified in ALARM TIME, the

 

 

point goes into an alarm state (ON); the red LED is illuminated, the alarm

 

 

sounds, and the message “FLOW LOW” displays at the ODP.

06

HIGH ALM

This point displays an ON or OFF status. When the exhaust flow goes above the

 

 

value specified at HI ALM LMT for the item specified in ALARM TIME, the point

 

 

goes into an alarm state (ON); the red LED is illuminated, the alarm sounds, and

 

 

the message “FLOW HI“ displays at the ODP.

07

EMER ALM

This point displays an ON or OFF status that indicates if the EMERGENCY

 

 

PURGE button on the ODP has been pressed. When the operator presses the

 

 

EMERGENCY PURGE button, the point is ON, the red LED is illuminated, the

 

 

alarm sounds, and EEE and EMERGENCY MODE display at the ODP. If pressed

 

 

again, then the point is OFF. This point can be commanded by a field panel.

08

GEN FAILURE

Indicates a hardware failure (e.g., the pressure sensor) with an ON or OFF

 

 

status. The red LED is illuminated; the alarm sounds, and FFF and GENERAL

 

 

FAILURE display at the ODP.

10

HI ALM LMT

The value above FLOW STPT, in percent, at which the red LED and audible

 

 

alarm are activated on the ODP. This point is the setpoint for HIGH ALM. Valid

 

 

values: 100 through 255%.

 

 

 

11

HI WARN LMT

The value above FLOW STPT, in percent, at which the yellow LED is illuminated

 

 

on the ODP. Valid values: 100 through 255%.

 

 

 

12

LOW WARN LMT

The value below FLOW STPT, in percent, at which the yellow LED is illuminated

 

 

on the ODP. Valid values: 0 through 100%.

13

LOW ALM LMT

The value below FLOW STPT, in percent, at which the red LED and audible

 

 

alarm are activated on the ODP. This point is the setpoint for LOW ALM. Valid

 

 

values: 0 through 100%.

14

EMER TIMER

When EMER ALM is set to ON, the time set for EMER TIMER is used as the

 

 

length of time the EXH FLOW is commanded to full flow (the exhaust flow control

 

 

device is full open). After the time in EMER TIMER times out, the EXH FLOW is

 

 

controlled to the value set in EMER STPT. Valid values: 0 through 32, 767

 

 

seconds.
