New Speed De-Rate Option
With the latest DCT and Brain versions there is a new option to add a condition to derate the top speed of the engine. One common case is to use manifold temperature to derate the top speed, so that the engine slows down when the temperature is high then automatically speeds back up when cool. See Dynamic Speed De-Rate
Tip: Improving Modbus Reads on EIM
With the latest EIM version (2.26) there is a read delay option added to the Modbus setup. By setting this value to 75 ms the read reliability can be much improved. This helps resolve issues with remote data coming in and out. EIM Read Fix

Tip: Light Tower Usage in Test Mode
Did you know the panel light tower can be used during test mode to help with switch tests? Test mode is started by going to Brain/Annunciator - Testing Mode and selecting "Start test mode", which will begin a countdown timer. During the test state if any digital input (e.g. float switch) goes to faulted the light tower will flash yellow once. When it goes unfaulted the tower will flash twice quickly. This can be used to verify a switch works from around the skid. The time of last fault will also be logged on the "Previous Fault Times" button on that same page to also help with testing.
New Telematics Support Number
There is a new number available for all things related to telematics support: 307-209-4566. This number can be called or texted for activations, troubleshooting, etc. For less urgent items the email address telematics@emittechnologies.com can also be used.
Upcoming DCT Change for Panel Switch Connections
A new version of the DCT will be released soon that has the panel switches (start, stop, reset, and speed switches) wired to the screen rather than back to the Brain module. This will help simplify wiring and free up digital inputs on the Brain module.
The new screen can still be used on old panels because the system will detect the wires are still running to the Brain module instead. However, if a panel with a new DCT of this style is swapped it will be important to use another new-style DCT. For more information, see DCT Panel Switch Connections.

Brain PID glitch resolved
Versions 2200 and 2209 of the Brain (Annunciator) software had an issue where on rare occasion the output of a PID loop would jump to a high or low value. This was fixed in version 2305, which can be found with other updates here: Software Updates
Tip: Telematics config backups
Did you know that DCTs on active telematics backup the Brain config once per day? On the Connect Portal the "config" tab of a unit can be used to view when configuration items were changed. Additionally, EMIT can provide a copy of a past config if needed by emailing telematics@emittechnologies.com
Tip: Lube Rate Monitoring
On both the DCT and EIM the system can be set up to monitor the divider block lucubration rate as a percentage of the rated value. This can be set up under Annunciator/Brain - Input Setup - No Flow. The system will track the rate as a percentage: if under 100% the unit could be under-lubricating even though the alarm isn't being reached. If over 100% the unit could be wasting oil. Info on how to set up on an EIM is here, and the DCT page works the same : Annunciator Setup - No Flow Monitoring

New DCT Version Released - 1.52
A new DCT version is now available here: Software Updates
Changes with this version:
- The dual recycle loop now has a manual mode
- No-flow monitoring can now track pints per day of oil usage
- ECU information page shows a few new sensors
- Remote sending of discharge temperatures now works better with alternate input names. For example, if some units on telematics are missing cylinders 1 and 3, this likely will fix the issue.
New EIM Version Released - 2.26
There is also a new EIM version available at the link above.
Changes with this version:
- Ported blowdown to header, dual recycle, and dual speed control options from the DCT to the EIM
- Datalog rate can now be adjusted
- Support for the EMIT ECU added
- Idle permissive can now use a few engine sensors as the threshold
- Input calibration ported from DCT
- Issue has been fixed where the CAT error code was not collected correctly for remote data. Recommend updating EDT as well to v1871 to improve pulling of error codes.
- Remote sending of discharge temperatures now works better with alternate input names
New Data Relay Troubleshooting Guide Available
A new troubleshooting guide is available that covers common fixes for setting up a Data Relay. It can be found here EDR Troubleshooting Guide
