DPF20

功能

具体描述

Scaling

Multiply, divide and preset values

Alarms

1. configure a secondsetpoint inthe samealarm, tocreate “alarm windows”
2. configure independent activation anddeactivation delays
3. configure hysteresis
4. configure alarm toactivate as high or low
5. failsafe function – normally closed relay requires activation fornon-alarm condition
6. latched alarms function – operator reset required
7. Counter Reset, Stop or Continue
8. Configurable hysteresis

Powerup delay

Allows for adelay in thestart-up time after powering the instrument. During this time the instrument performs no measurementor control.
Ability toreset the display count on instrument start-up.

DisplayBrightness

Select from5 levels of LED intensity.

Password

Password protect the configuration menu.
This blocks access to the instrument set-upparameters, but the operator can still access set-point values.

Max /min memory

Front panel key selection of display minimum ormaximum values

SensorType

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

Triggersense

Simple selection of the optimal trigger level forthe sensor input. The display indicates up or down reflecting the status ofthe input signal level. When the LED changes state continuously the optimaltrigger level has been achieved.
