Units that are a critical part of your plant, in a cold area or are powered down regularly will require battery changes every 1-2 years.ĭon’t hesitate to contact Garland Instruments if you require a technician to visit your site to help retrieve backups, change batteries and check your equipment for obsolete parts. The Batteries are non rechargeable and will drain over time. Are you regularly changing your Batteries?īatteries can be found in PLCs, HMIs, and Servo controllers. Points to always consider with your Automation products.Ĥ. We loaded the old program and watched the whole system come back to life along with some very happy faces 😁😁 We replaced the battery and luckily we had a backup of the program from a previous visit. As we suspected the PLC battery had drained and the PLC lost its program. As the PLC was very old, we had brought an FX5U PLC just in case, but we knew this PLC is hard to kill. We received the call and headed up with a few spares. Unpowered in a corner for 2 years until production ramped back up and it was required urgently again only to find none of the outputs were coming on.

This is a PLC program from the 80s and the software could automatically upgrade the program from MEDOC to GX Developer to GX Works2 to GX Works3. Amazingly the software was upgraded with ease into GX Works 3 😳. The PLC itself was still working but we decided it was time to upgrade the PLC to Mitsubishi’s latest FX5U. But it done the job and downloaded the program from the PLC with no issues. This software is so old it doesn’t know what a mouse is. The program was retrieved with an old version of MEDOC. Can you believe it, all that time controlling the machine until one day it would not start. This lovely bit of kit was hidden away at the back of a machine and working away, doing its job, day in, day out without anybody even knowing it was there.

With the new A840 drive, we could control the starting current, torque and reduce the speed to prevent the machine from starting and stopping all the time.

The solution was to install Mitsubishi’s A840 22kw advanced Variable Speed Drive that we had in stock and 2 x E740 11kw Variable Speed Drives. The VSDs in the picture were part of an emergency install over a weekend to replace a 22kw Soft Start that had failed due to constant stopping and starting and 2 x 11kw DOLs that we’re due to be upgraded. Some Soft Starts only allow for a certain amount of starts per hour and the unit installed had a limit of 10 starts per hour for Standard Duty applications and 5 starts per hour for Heavy Duty applications. Soft Starts are great at reducing starting current and reducing mechanical stress on the machine during startup but a VSD gives much more control.
