Tips & Tricks
Here you will find instructions on how to set up and operate our products, as well as troubleshooting tips.
How large is the hysteresis, or can it be adjusted?
A hysteresis describes the distance from the switching-on and cutting-off points in relation to the input parameter. Hysterisis prevents constant short switching-on and cutting-off operations caused by an unsettled input or measured value. If hysteresis is configured appropriately it is referred to as two-point-control.
In the case of our monitoring modules the switching point and the hysteresis can be adapted to your requirements by means of one 12-turn potentiometer each.
How many contacts are available to me?
Two switching outputs are available in each of the DG monitoring modules. The two outputs can be configured separately. The switching point and the switching hysteresis can be configured at the front of the device using a 12-turn potentiometer. The switching status is displayed by a yellow LED on the front of the housing.
The effective direction and mode of operation can be switched by using the DIP switches. Both switching outputs can configured as MIN or MAX alarms.
The relay contacts switch high-output loads, optionally as N/O contacts or N/C contacts.
Are active switching states displayed?
Yes, the current switching state is indicated by a yellow LED at the front of the device.
The effective direction and mode of operation can be switched by using the DIP switches. Both switching outputs can be configured as MIN or MAX alarms. The relay contacts switch high-output loads, optionally as N/O contacts or N/C contacts.
Monitoring process variables
It is frequently expedient to additionally monitor measured process variables in the form of standard signals with additional alarm contacts in order to be able to report a plant failure.
You can monitor industrial standard signals with the alarm units from DRAGO Automation. You have 2 limit values available to you, which can be configured for the switching point and the hysteresis. The relay contacts switch high-output loads, optionally as N/O contacts or N/C contacts.
Monitoring of the electrical energy supply
Current and voltage alarm units from DRAGO Automation are available for monitoring currents and voltages in supply networks.
Measuring ranges of 1 or 5 A for the current alarm unit and 24, 48, 120 or 250 V for the voltage alarm monitor can be monitored by means of 2 limit contacts. With this you can implement a pre-alarm warning and a main alarm or achieve a MIN / MAX alarm signal.
The relay contacts switch high output, optionally as N/O contacts or N/C contacts.
