In many processes, metering is effected periodically or is initiated by external events. In almost any case collateral actions must be triggered in advance or with delay such as the powering of a mixer before starting metering. Or a metering station is to be added to an existing process and shall operate as an autonomous unit.
The Process-Timer was designed especially for these tasks, that so far could only be realized with programmable logic controllers. The feed rate (stroke frequency) as well as the mode of operation of the pump can be adjusted or changed via the Process-Timer. Additionally, both optional relays can be integrated into the programm for controlling peripheral devices. As this is effected entirely independently from the adjusted metering times, beside the examples listed above, monitoring tasks (e.g. alarm, if no control contact is ascertained within a defined time period) can be solved by means of the Process-Timer.
Modes of Operation
Time-controlled operation of the pump will have the Timer work every hour, daily, on weekdays only, on weekends, weekly or bi-weekly as per your demand. Beside the starting and stopping of the pump, the operation mode can be changed and one or two of the relays (supplied on demand) can be controlled. Thus, for instance, it will be possible to switch on the mixer before starting metering and - if required - even let it run after the pump has stopped
Entirely new perspectives are granted with the event-controlled Timer Version. Here, a program is started after an external start-contact or at a point in time defined in advance. This program can consist of up to 80 different points such as pump start/stop, switch to external contact operation for a defined time period etc. Here, too, relays can be integrated into the program.
With the overlapping of the two versions almost no limits are set to the application possibilities. The integrated timer can completely replace program controls that operate with conventional timer-clocks. Beside cost-savings, in addition to, all the space saving is an advantage - and this all at protection class IP 65!
