ALARM PROGRAMMING INFORMATION

OPERATION MANUAL

E.Latched Output: Enabling the Latched Output bit will cause any active alarm to become latched and held active even if the alarm condition clears. Any ‘latched’ alarms can be cleared during RUN mode by pressing the EDIT key (if the active alarm(s) are no longer active). After pressing the EDIT key, any latched alarms that are no longer active will be cleared and any alarms that are still active will remain latched.

F.Digital Out1: Enabling the Digital Out1 bit will cause the digital output channel (OUT1) to change to the LOW state if any alarm is active.

þNote: The OUT1 (and OUT2) channels are ‘open collector’ style outputs. The user must externally connect an active pull-up voltage to the output pins for proper operation. The maximum external pull-up voltage that can be applied to the output pins is 24 volts DC.

G.External Constants: Enabling the Ex ter nal Con stants bit will cause the pro grammed con stants for temperature or pressure to be used in the mass flow calculations if ei ther the ex ter nal temperature or pres sure in puts are se lected and in fault con di tions.

9.4Alarm ‘STATUS’ Word Definition

The ALARM STATUS word indicates which alarms are active during RUN mode. Since the individual binary bits cannot be displayed on the LCD, the decimal word equivalent representing the active alarm status bits is displayed. The individual alarm status bit assignments and the associated binary values are shown below.

þNote: If alarms are ac tive, the alarm ICON on the LCD will be lit and the ALARM sta tus value will be dis- played ev ery 10 sec onds. The user may also use the INC/DEC keys to ac cess the alarm sta tus value on the LCD.
