- Page 4 Safety: The Nolatron Start Bar is not intended for use without adequate “point of operation” safety guards, which must be provided following OSHA regulations and ANSI standards to protect the operator. The operator must ensure the bar is properly installed, inspected and operated. Failure to comply could result in serious bodily injury and/or property damage.

Page 5: Installation
Warning! It is necessary to locate and install the Start Bar in accordance with OSHA machine guarding distance calculations which can be found in 29 CFR 1910.217. Users must also install point of operation guarding devices, compliant with OSHA regulations, ANSI standards, and any other machine safety standard that applies to the specific industry such as light curtains, pressure mats, etc. - Page 6 Operation: The Start Bar will perform a system test before every machine cycle. The test cycle will require approximately one second to complete. Then the Ready indicator will light and a machine cycle can be started. In order to begin a machine cycle, both hand switches must be touched concurrently within a half a second.
- Page 7 Normally, this requires a pair of positive guided relays. The normally closed contacts of the relays must be monitored by the ATD control. Please call Nolatron for technical assistance on how these relays are configured to operate in conjunction with the Start Bar.
- Page 8 Wiring the Hold switch: An optional Hold switch can be used to allow the load to remain energized after the hand switches are released. This feature is useful for applications that have long machine cycles. The Hold switch is normally open and must not be closed until the operator can no longer reach into the point of operation.
- Page 9 Safety Testing Procedure: After the Start Bar is installed, an initial safety test must be performed by a qualified person who is appointed by the employer. This testing procedure is used to ensure that the Start Bar has been wired and is functioning properly. The testing procedure should be carried out periodically and the machine must not be used if the Start Bar ever fails the test.
