M00352 Limit Board Installation & Adjustment on Existing Controllers
■The O. Thompson M00352 Limit board is designed to be an exact replacement of the older style M00118 Limit board. The M00352 Limit board uses a processor to monitor car speed and the status of the hoistway limit switches. If the car speed exceeds that which is safe for an approach to the top or bottom terminal floor, the Limit board will open the safety circuit, removing power from the brake and hoist motor.
■The following is an explanation on installation and adjustment of the board. The board can be installed in one of two ways. If you have an existing installation, and do not wish to activate the speed clamping function, follow the procedure that is outlined for an existing installation. If you wish to activate the clamping, follow the procedure for a new installation. The board will automatically detect if the speed reference is present, and if not, will not clamp the reference, but rather open the fault circuitry.
