Volkmann now offers a line of electronic timers for electro-pneumatic operation of its Multijector VS and PPC series of vacuum conveyors. The basic ET3 and ET4 models control conveying cycles using a small PLC controller. Suction and discharge times are easily changed in the adjustment menu via the controller’s keyboard. Settings are password protected and are adjusted to suit the product being conveyed and the required transfer rate during start up. Both controllers have the capability to interface with the client’s PLC (permissive) where the operator initiates conveying or with the client’s level probes where the interface is fitted in the receiver to dictate suction cycle by product quantity, located in the source hopper or vessel to confirm material presence for conveyance, or used beneath the receiver valve in a filler hopper or feeder where conveying is initiated when the level falls below a designated level.
