PRODUCT SAFETY ADVISORY
Notice of Potential Unsafe Condition
Rockwell Automation issues a Product Safety Advisory when it identifies a product(s) anomaly that may potentially cause harm to personnel, capital equipment loss or environmental damage. Immediate action is required as identified below.
ProSafe Electronic Timed-Delay Series B Unit with Ability to Deliberately Override Timed-delay Safety Function
Reference: 2017-11-002
Date: November 2017
This Product Safety Advisory informs you of a potential anomaly that exists with the ProSafe® Trapped Key Switch with Electronic Timed-delay unit, Catalog numbers 440T-MSTU* and 440T-MDTU*. Operators may be able to take deliberate actions to override the time delay function by power cycling the ProSafe unit during the time delay period.

1Important – Rockwell Automation may continue to ship Series B product with an included product statement pending release of Series C correcting this anomaly. These shipments may include specific catalog numbers not listed in the table above, but part of the 440T-MSTU* and 440T-MDTU* product families. Customers are advised to read all product literature and warning labels when receiving new product. If your system configuration requires the use of Series C product, all Series B may be replaced with Series C.
For installed product, the product catalog number and date of manufacture may be found on the product nameplate. The catalog number will be at the bottom of the label and the manufacturing date will be in the DATE file of the format YYYY/MM/DD, where YYYY is the year, MM is the month code, and DD is the day of the month.
In the example shown to the left, the catalog number is 440T-MSTUE100A and the date of manufacture is 2017/09/18, or September 18, 2017. This product matches the product identification information and would be subject to this notification.
Note – The product nameplate does not contain the series designation. Therefore, installed product may only be identified by the catalog number and manufacturing date code, not the series designation. As of the release of this notification, Series B product was manufactured between February 8, 2017 (2017/02/08) and October 28, 2017 (2017/10/28). Product may continue to be manufactured and shipped with an attached warning label until Series C product correcting this anomaly is available. If you have installed product where the series designation is not

available and the date code is after 2017/10/28, please contact Rockwell Automation Technical Support to determine if your product is Series B or Series C. Reference this Product Safety Advisory PSA 2017-11-002 when requesting support.
For new product still in its original carton, the product catalog number and series number may be found on the product carton label. The catalog number will be in the CAT field and the series number in the SER field.
In the example shown to the left, the catalog number is 440T-MSTUE110A and the series is B. This product matches the product identification information and would be subject to this notification.
– Description –
Important – Product functionality is not affected by this anomaly. The time delay function works as specified when properly installed and operated. This notification addresses conditions where the operator may be able to take deliberate actions to override the time delay safety function.
The time delay safety function of the ProSafe trapped key switch is designed to provide time for equipment to reach a safe state before allowing the trapped key to be removed. If the trapped key switch is power cycled while the time delay function is in operation, the time delay will reset when power is restored and the switch will immediately allow the trapped key to be released, even if the time delay period has not fully elapsed.
– Temporary Workarounds –
No workaround has been identified. Customers are advised to put safeguards in place to prevent operators from power cycling the device during the time delay operation.
– Correction –
Important – You are only affected if your system design allows for operator power cycling of the trapped key switch during the timed delay period. If your system design is such that it is not possible for the operator to power cycle the switch, you are not affected and no action is required on your part.
If you have determined you may be affected by this anomaly, the trapped key switch must be replaced with a Series C unit. Rockwell Automation is currently working on a correction to this anomaly and expects to have Series C product correcting this anomaly by the end of calendar 2017. When available, contact your local Rockwell Automation Distributor or Sales Office, or other place of purchase, to request replacement product. Make sure to reference this Product Safety Advisory PSA 2017-11-002 when requesting replacement product. When you receive

replacement product, be sure to verify the replacement is identified on the carton label as Series C.
