Feature

Description

Scaling

Multiply, divide and preset values

Alarms

• Configure a second setpoint in the same alarm, to create “alarm windows”

• Configure independent activation and deactivation delays

• Configure hysteresis

• Configure alarm to activate as high or low

• Failsafe function – normally closed relay requires activation for non-alarm condition

• Latched alarms function – operator reset required

• Counter Reset, Stop or Continue

• Configurable hysteresis

Power Up Delay

Allows for a delay in the start-up time after powering the instrument. During this time the

instrument performs no measurement or control. Ability to reset the display count on

instrument start-up.

Display Brightness Select from 5 levels of LED intensity.

Password

Password protect the configuration menu. This blocks access to the instrument set-up

parameters, but the operator can still access set-point values.

Max/Min Memory

Front panel key selection of display minimum or maximum values

Sensor Type

The fast and simple way to configure a sensor. Select from a predefined list Eg. NPN, PNP,

Namur, pick-up, inductive, etc. The instrument will automatically configure the required

parameters for the selected sensor (pull-up / pull-down resistors, trigger level, excitation

voltage, etc)

Trigger Sense

Simple selection of the optimal trigger level for the sensor input. The display indicates up or

down reflecting the status of the input signal level. When the LED changes state

continuously the optimal trigger level has been achieved.
