ANALOG IN MAIN/ALT SELECT RELAY: Select the output relay that is to be used to multiplex two analog input signals to the PQMII. If this setpoint is “Off”, the MAIN analog input setpoints will be used unless a switch input assigned to SELECT ANALOG INPUT is activated. For more information on multiplexing two analog inputs using one of the PQMII output relays, refer to 2.2.8 Switch Inputs (Optional). • ANALOG IN MAIN/ALT NAME: This message allows the user to input a user defined 20 character alphanumeric name for the MAIN and ALT analog inputs. To enter the names, perform the following steps: Z Allow access to setpoints by enabling setpoint access. Z Select the Analog Input name message display under the S2 SYSTEM SETUP ÖØ ANALOG INPUT setpoints group. Z Use the VALUE keys to change the blinking character over the cursor. A space is selected like a character. Z Press the ENTER key to store the character and advance the cursor to the next position. To skip over a character press the ENTER key. Z Continue entering characters and spaces until the desired message is displayed. If a character is entered incorrectly, press the ENTER key repeatedly until the cursor returns to the incorrect position and re-enter the character. • ANALOG IN MAIN/ALT UNITS: This message allows the user to input a user defined 10 character alphanumeric name for the MAIN and ALT units. To enter the units, perform the same steps as shown for analog input name. • MAIN/ALT 4 mA VALUE: This message appears for each analog input and allows the user to assign a numeric value which corresponds to the 4 mA end of the 4 to 20 mA signal range. • MAIN/ALT 20 mA VALUE: This message appears for each analog input and allows the user to assign a numeric value which corresponds to the 20 mA end of the 4 to 20 mA signal range.

ANALOG IN MAIN/ALT RELAY

 Analog input MAIN and ALT detection can either be disabled, used as an alarm or as a process control. Set this setpoint to OFF if the feature is not required. Selecting “Alarm” causes the alarm relay to activate and displays an alarm message whenever a MAIN or ALT analog input condition exists. Selecting an auxiliary relay causes the selected auxiliary relay to activate with no message displayed. This is intended for process control. • ANALOG IN MAIN/ALT LEVEL: When the measured MAIN or ALT analog input meets or exceeds the level set by this setpoint, a MAIN or ALT analog input condition will occur. • ANALOG IN MAIN/ALT DELAY: If the MAIN or ALT analog input meets or exceeds the ANALOG IN MAIN/ALT LEVEL setpoint value and remains this way for the time delay programmed in this setpoint, an analog input condition will occur. If the ANALOG IN MAIN/ALT RELAY setpoint is set to “Alarm”, the alarm relay will activate and the ANALOG IN MAIN/ALT ALARM message will be displayed. If the setpoint ANALOG IN MAIN/ALT RELAY is set to “Aux1”, “Aux2”, or “Aux3”, the respective auxiliary relay will activate and no message will be displayed after the delay expires.
