Enter the reset action of the output. See figure for details.

Auto

= Automatic action; This action allows the output to automatically reset off

at the trigger points per the Setpoint Action shown in Setpoint Output
Figures. The “on” output may be manually reset (off) immediately by the
front panel

RST

button or user input.The output remains off until the trigger

point is crossed again.

LAtCH

= Latch with immediate reset action; This action latches the output on at

the trigger point per the Setpoint Action shown in Setpoint Output Figures.
Latch means that the output can only be turned off by the front panel

PARAMETER MENU

The Setpoint Output Parameters are only active when an optional output

module is installed in the meter.

Enter the setpoint (output) to be programmed. The

n

in the following

parameters will reflect the chosen setpoint number. After the chosen setpoint
is completely programmed, the display will return to

SPSEL

. Repeat steps for

each setpoint to be programmed. Select

NO

to exit the module. The number of

setpoints available is setpoint output card dependent.

Enter desired hysteresis value. See Setpoint Output Figures for visual

explanation of how setpoint output actions (balanced and unbalanced) are
affected by the hysteresis. When the setpoint is a control output, usually
balanced hysteresis is used. For alarm applications, usually unbalanced
hysteresis is used. For unbalanced hysteresis modes, the hysteresis functions on
the low side for high acting setpoints and functions on the high side for low
acting setpoints.

Note: Hysteresis eliminates output chatter at the switch point, while time delay

can be used to prevent false triggering during process transient events.

Enter the time value in seconds that the output is delayed from turning on

after the trigger point is reached. A value of 0.0 allows the meter to update the
output status per the response time listed in the Specifications.

Enter the time value in seconds that the output is delayed from turning off
