CYCLE LOCK SYSTEM SOLUTION MECHANICAL CHARACTERISTICS Nominal widths: customer specific Temperature range: Permissible operating pressure: Permissible differential pressure: ELECTRICAL CHARACTERISTICS Power supply: Operation / visualisation: Protection class: Temperature range for lock: Temperature range for control: Cycle locks for holding bulk materials and powdered media with an automation unit for venting and bleeding. GENERAL NOTES - Very variable application because all EBRO valves can be integrated into the system - Communication using conventional signal technology (binary inputs and outputs) - Possible to integrate into existing control systems without any problems - Remote access via Ethernet (optionally via Wlan) using the integrated web visualisation tool - Self-learning adaptation of the activation times to fluctuations in the process values - Intelligent service management system for preventative maintenance - In order to increase the operational availability of the system, changes in the activation times for the valves (e.g. due to blockages or valve wear) are reported - Stand-alone operation possible - All standard field bus interfaces available - Control unit detachable - ATEX Zone 1/21 applicable FIELDS OF APPLICATION e.g.: - Dosing and discharging bulk goods - Pneumatic conveying technology A Phönix PLC with a touch panel is used to operate and visualise the processes. - Power plant technology - Weighing technology - Bagging plants Cycle Lock

CYCLE LOCK SYSTEM SOLUTION FUNCTIONAL SCHEMATIC INITIAL STATE The medium is in the current process and shut off on the inlet side. Before every individual cycle, the output valve is opened for safety reasons to ensure that any possible residual media can fall out of the filling pipe. The medium falls into the filling pipe and is held on the output side. The filling time can be freely selected. The filling process can be cancelled based on the volume of material required using a filling level sensor. INTERMEDIATE STATE Once the filling level has been reached, the inlet valve closes. The...

CYCLE LOCK SYSTEM SOLUTION PRODUCT SPECIFICATION 1. Isolation valve at input side with a pneumatic rotary actuator and stop position monitoring: In principle, any valve – butterfly valve, gate, pinch valve or ball valve – can be used for the cycle lock. Both components (in this case butterfly valves) are screwed together with the filling pipe in the factory. It is preferable to use single-acting (spring-reset) pneumatic actuators of type EB-SYS for operating the valves. Stop position monitoring takes place using limit switch boxes of type SBU with mechanical or inductive limit switches. 2....

CYCLE LOCK SYSTEM SOLUTION OPERATION AND VISUALISATION The main screen makes it possible to easily monitor the ongoing process and select the operating modes. In the main menu, there is a manual operation option, all parameter settings are adjustable and the current process values can be observed. The cycle can be flexibly adapted to the relevant process in the menu section “Process times”.
