Schneider Electric VW3A1101 Altivar remote graphic terminal

VW3A1101: Altivar remote graphic terminal, 240 x 160 pixels

The VW3A1101 is a Schneider Electric remote graphic terminal for Altivar variable speed drives. It is a display and keypad unit with a 240 x 160 pixel screen showing eight lines of messages, built to be mounted on the door of an enclosure with IP54 protection. Through it an operator can control, adjust and configure the connected drive, save and download configurations and read current values. Seven Star LLC supplies the VW3A1101 in Oman and the GCC as an independent supplier based in Muscat.

The title of VW3A1101 describes the product directly: remote because it sits away from the drive, graphic because it draws on a pixel matrix instead of showing digits only, 240 x 160 pixels for the resolution and IP54 for the front protection degree. The datasheet classes it as a display terminal in the display and signalling accessories category.

What is not included with VW3A1101

The datasheet describes the terminal itself, not the connection cable, the drive or the door-mount hardware. Please state the drive reference and the distance between drive and terminal in your enquiry so the supply of accessories can be confirmed. We do not guess at accessories that the datasheet does not list.

If you already have drives of several types in the same plant, tell us all of them; the list of ten compatible ranges above often means one terminal type can serve a mixed fleet of drives.

Selection checklist for VW3A1101

• Confirm the Altivar drive family from the ten listed.
• Check that the drive needs a remote terminal and does not already have one.
• Prepare the door cut-out so IP54 is kept.
• Identify the cable and connector between drive and terminal.
• Pick the display language that the maintenance staff will use.
• Confirm the enclosure temperature is below 50 °C.
• Decide whether you want the terminal for cloning configurations across machines.

Door mounting and protection of the VW3A1101

The terminal is designed for mounting on the door of an enclosure, where the operator sees it without opening the cabinet. The datasheet lists IP54, so dust ingress is limited and splashing water from any direction is withstood, provided the door cut-out and the fixing are made as the product instructions say. Operating temperature is listed from -15 to 50 °C, and the net weight is 0.145 kg.

A terminal on a door has to work in the real temperature of the panel front. In Oman, panels in direct sun or in rooms without cooling can approach the upper limit, so check the cabinet temperature against 50 °C. Keep the front clean and avoid solvents on the screen.

What the VW3A1101 lets an operator do

Three functions are named in the datasheet. The first is to control the drive, which means start, stop and speed reference from the door when the drive is set up for it. The second is to adjust and configure, in other words to read and change parameters in the menu. The third is to save and download configurations, so one terminal can capture the settings of a drive and carry them to a replacement unit of the same family, speeding up commissioning of identical machines.

The display shows 8 lines, which is enough to read a parameter name and value together without scrolling through many pages. Six user languages are listed, so the terminal can be switched to the language of the maintenance team.

Commissioning and handling of VW3A1101

When you commission a drive, the terminal is the interface for the first parameter setup. Record all changes from the factory defaults, and use the save function to store the final configuration. If the drive is later replaced, the saved set can be downloaded to the new unit, which shortens downtime. It is good practice to keep a note of the date and software version of the stored set.

Spare terminals are useful where the front panel is exposed to wear, since a damaged display or keypad is an inconvenient reason to stop a machine. The unit can be changed without altering drive settings if the configuration is held in the drive itself.

Use of VW3A1101 in Oman and the GCC

Variable speed drives control pumps, fans, compressors, conveyors and cranes across Oman and the GCC, in water, oil and gas, building services and manufacturing. A graphic terminal on the panel door helps operators in plants where drives sit in a motor control room or a skid-mounted cabinet. The datasheet gives a temperature limit, so check against local panel conditions, and consider the lifetime of the screen under constant use.

Drive ranges that the VW3A1101 supports

The datasheet lists compatibility with ten Altivar references: Altivar 312, 61, Lift, 32, Machine ATV320, 312 Solar, 212, 71, 61Q and 71Q. This is a long list for one accessory, but it does not mean every drive uses it the same way. Some drives have a built-in keypad and use this unit as a remote option, others rely on it for the first display of parameters, and the connection details differ between ranges.

Before you order the VW3A1101, check the drive reference and the connection arrangement in the drive manual. We confirm the exact drive reference with you when answering an RFQ, because a terminal for the wrong range wastes site time. Also confirm the cable needed between the terminal and the drive, which is not part of this datasheet.
