This coffee grinder timer controller controls the run time of the grinder. It can be used for grinder with a on/off switch, or with a timer switch. For grinders with internal contactor such as the Mazzer with automatic switch (On/Off + Start), our model J72MA
should be used.
The controller has three buttons on the top of the box. Two of them can be programmed to run the grinder for a specific duration (from 0.01 second to 99 minutes). User can set one button for single shot and the other for double shot espresso. The third button is for manually controlling the grinder. It will turn on the grinder when pressed. The time duration of the manual control is displayed. It can be used for fine tuning the single or double shot timer setting.
The controller also has an accumulative timer that accumulats the run time of the grinder until it is reset by the user. The timer unit is programmable. User can set it to second, minute, cups, or convert it to weight units (such as gram, once, or pound) with a simple calibration. It is a useful feature for bookkeeping in a commercial coffee shop .
For grinder that has a spring loaded switch or a mechanical timer switch, user needs to find a way to keep the switch at on position. This link provide examples on how to keep the switch at on position for Rancilio Rocky and Mazzer with Time switch.
The output socket will accept either US 120 standard plug (NEMA 5-15P), or European standard plug (CEE7/7). The output voltage is the same as the input voltage. In other words, if the controller is plugged into a 120 V socket, the output will be 120 V. If it is plugged into 220 V socket, the output will be 220 V. The input socket is the standard socket used on computers (IEC320 C14). The controller internal relay is rated 10 A for 120V and 7 A for 240 V (the rating is for resistive load. For the inductive load such as motor, the rating is lower, depending on the inductance).
