What are the ways that TOGGLE-AIRE® Series presses can be controlled?

1. BEM Impulse Mode.
In operation, this control method requires momentary actuation of the Synchro-Sig Anti-Tie Down Two-Hand Controller (SS-PB) unit to initiate the press cycle. Once the press has been activated, the ram will descend until it reaches the bottom of the stroke where the linkage stops against a positive stop before the press will reverse. The ram will not return up until it reaches maximum strength and travel. The BEM Impulse mode of operation insures a very accurate stroke and helps guard against inattention of the operator, loss of air pressure, improper loading etc., and maintains the quality of the work being performed. Repeatability in this mode is plus or minus .001″

2. CSR-G2 (Constant Signal Required Mode, Version 2) CURRENT STANDARD CONFIGURATION
This method of control requires that the operator’s hands be held down on the SS-actuator for the full duration of the down stroke of the press. If one or both hands are removed before the press ram reaches bottom the ram will instantly reverse and return to the top of the stroke and await a new signal from the two hand unit. This method of operation is especially useful in applications requiring slow ram speeds or special loading considerations. As the standard configuration, operators are told to keep both hands on the controller until the press automatically cycles. Once the ram has bottomed, it will automatically reverse and retract, insuring a complete and accurate part, while maintaining a safe operation.

3. SAR Stall Activated Reverse.
In this method of control the press ram reverses automatically as soon as it stalls, regardless of its position relative to the bottom of the stroke. It is quite useful in coping with tolerance variations of parts to be assembled, die castings, etc., as the ram does not have to reach absolute bottom before it will retract. it is important to remember that this can be used only if you have established that the press will have enough power to do the job in question throughout the full range of your parts, that is, both ends of the tolerances. See the RAM FORCE tables for each model to determine how much power you will have at your disposal. The SAR Stall Activated Reverse Mode is also very useful in delicate jobs. By playing the air supply pressure against the depth setting of your tools you can, in effect, reverse the press when a desired maximum force has been developed and create a very delicate stroke which will not damage fragile parts, etc.

4. CSR (Constant Signal Required)
This standard method of control for our DIRECT-AIRE® Series presses means the ram stays down as long as the operator keeps their hands on the controller. When removed, it retracts.
