1 Rhino SD/XD Pump Overlap Time-Delay Module Description See Figure. The Rhino SD/XD Pump Overlap Time-Delay module consists of a pneumatic time-delay valve () that is installed into the drum empty circuit. When a drum empty condition occurs, both pumps must be operating to perform a standard changeover from the active to the standby pump. The time-delay valve delays the shutdown of the air motor on the active pump to prevent loss of output pressure. Pump overlap is necessary if a drop in supply pressure to the dispense system is seen during the pump changeover sequence. This typically occurs in systems that use short hoses or header system circuits. Installation Adjustment See Figure. The time-delay valve is adjustable from 0 30 seconds. NOTE: The overlap time is the amount of time that both pumps are active. Turn the adjustment screw () clockwise (in) to increase the overlap time. Turn the adjustment screw () counterclockwise (out) to decrease the overlap time. NOTE: Turning the adjustment screw fully counterclockwise (out) disables the overlap time and may produce a momentary drop in output pressure when the standby pump comes up to speed. WARNG: Allow only qualified personnel to perform the following tasks. Follow the safety instructions in this document and all other related documentation. See Figures and to install the time-delay valve into the drum empty circuit. DECREASE CREASE Figure Pump Overlap Time-Delay Module 006 Nordson Corporation
