What storage technology is used?

PMVFUPS01 guarantees the necessary energy by accumulating it in capacitors, thus avoiding the use of batteries which require maintenance. _____________________________________________________________________ Other information on this topic Visit the website page dedicated to Backup power supply for interface protection units.

How long does it take to recharge PMVFUPS01?

A maximum time of 15s is required to fully charge the storage capacitors. The output voltage is present only when the charge is completed. It must be considered that the recharge is required at the very first switch on as well. _____________________________________________________________________ Other information on this topic Visit the website page dedicated to Backup power [...]

How to choose the interface and back-up switches to be coupled to PMVFUPS01?

PMVFUPS01 accumulates enough energy (200Ws) to correctly drive PMVF series interface protection, a BF or B series contactor by LOVATO Electric acting as an interface switch and the shunt release of the backup. The selection of the right contactor according to the AC3 power is suggested on PMVFUPS01 user’s manual. In case of third party [...]

How does the hour counter function work? How does it differ from the other functions?

The Hour counter function allows to count the working hours of a machinery and signal the reaching of a threshold by energizing the relay output, for example to signal a request of maintenance. The hour counter (expressed in hours) is updated and saved in the memory of the TMM1 NFC every 10 minutes and compared [...]

Are LOVATO Electric HMIs able to communicate only with LOVATO Electric devices?

No, our HMIs can communicate with all devices that have an RS485 / 232/422 / Ethernet port and support Modbus-RTU Master / Slave, Modbus-TCP Client / Server, SIEMENS S7 Ethernet, MTTQ, or OPC UA Client / Server protocols. _______________________________________________ Other information on this topic Visit the website page dedicated to HMI.

How many devices can I connect to an HMI?

There is no predefined maximum number, theoretically it is unlimited. From a practical point of view, the limit is conditioned by the number of devices allowed by the network in which they are located (eg RS485 network) and by the possible traffic congestion on the network itself. _______________________________________________ Other information on this topic Visit the [...]

Is it possible to manage the access permissions to the HMI to exclude some users from using certain functions?

Yes, by default there are already three levels of access that you can view by following the path: ProjectView> Security> doppio click su UserGroups These three user groups cannot be deleted or renamed, however you can change the authorizations and other settings. _______________________________________________ Other information on this topic Visit the website page dedicated to HMI.

Which are the advantages of the programming via NFC compared to the programming via potentiometers?

Programming in simple and fast way, ideal solution for the programming of several time relays in series: you can program just one time relay and then copy the same programming on the others TMM1 NFC very quickly. - Very high accuracy and precision in the time settings on the entire range (short and long scales), [...]

Which models of Lovato Electric time relays with potentiometers can be replaced by TMM1NFC?

TMM1NFC integrates 40 functions, included those of TMM1 (multifunction, 10 function), TMP (on-delay) and TMPL (flasher with independent timings). Moreover, the numbering of the terminals of TMM1NFC, which is identical to the traditional versions with potentiometers above-mentioned, makes it perfectly interchangeable with these models, without the need to modify the wiring diagram.  Here are some [...]
