New Product Features
PU-E Series Pickup – Extended Temperature Rating (8/18/09)
The PU-E Series Hall Effect speed pickup utilizes a sealed bearing in its design. The bearing lubricant has been upgraded to extend the low temperature operating limit to -50° Celcius. This change will be made on the fly and should be in place by the end of 2009. This is an across the board change – no special request or part number is required to receive this new lower temperature rating. Customers who need this low temperature rating are encouraged to call the Dart factory to verfiy the new lubricant is being used.
DP4 Series – New Pluggable Terminal Strip Option (3/20/09)
Euro style pluggable terminal blocks save time, tooling and expense during the control installation process. This popular option has now been added to the DP4 product line.
DM8000 – Software Update to Improve Zero Speed Action (1/23/09)
The DM8000 programmable rate meter is typically used in continuously or near-continuously running applications. It was discovered with the help of customer feedback that the product would display inconsistent readings when the input to the device went to zero. The software has been modified to force and hold the display to zero after a specified period of time after the pickup / encoder input goes to zero. Correct rate display will continue on the resumption of encoder (non-zero) input.
MD Series – Inhibit Function added (8/19/08)
Using the flexibility of a microprocessor-based design, the MD series software has been modified to include a double-click inhibit function. Refer to the MD Series instruction manual for more details. Customers save time and cost by eliminating the need to purchase and install an external Start/Stop switch for the drive.
250 Series – New Endplate option aids installation (2/9/09)
Customers using remote signal / switching with the 250G-E Series (enclosed) versions faced the issue of where to route the third (signal / switch) set of wires. Previously, the 250G-E Series was shipped with only two (2) conduit holes in the end plate. Dart recommends AC source power and DC armature voltage be routed separately during installation. Dart also recommends all signal wiring be routed separate of source and armature wiring. In these cases, three wiring routings through two holes, but all separate per Dart. With the aid of a customer, Dart re-designed the endplate to accomodate three holes. This need is only present with enclosed models. If you are using remote wiring to the enclosed 250G Series control in addition to source power and armature cabling, please ask the factory for an optional three (3) hole endplate when ordering.
