Electronic timer/counter STS 405

Timer and counter STS-405 is a microprocessor device that can operate as a 4-digit programmable counter with multiple input and output modes or a 4-digit timer with multiple time ranges and output modes as well as an 8-digit counter totalizer which counts incoming input pulses. The device has an input press (multiplier / divisor) for a counter function, input filters for both functions, and bank with set limit values, selecting which ones are active. Upon reaching the limit value, one of the two outputs, which may be relay or optocoupler, respectively responds.

Mode key: When you press this button for more than 3 seconds, enter the menu: „Initial setting level.” Short press to go to the next parameter in the current menu, remembering the previous one.
Shift key: When you press this button for more than 3 seconds, enter the menu: „Adjustment level.” When you briefly press the next digit (right to left), change the value of a parameter in the current menu or consecutively change (alternate) the parameter values.
Up key: Pressing this button for more than 3 seconds will enter the menu: „Function setting level.” When pressed briefly, it increases with one current value of the digit (0 – 9) that is currently changing.
Clear key: If you press this button for more than 3 seconds, enter the menu „Communications setting level.” By briefly pressing this button in programming mode, the current value of the parameter currently being changed is reset. pressing in the operating mode resets the display to „Present value display” and in „Total count” and „Set value display”

When one of the buttons is held uninterrupted for more than three seconds, it switches from operating mode to the parameter change mode in the current menu. After PASS —- appears in the display, mode changes to entering the access password, and Clear returns to the operating mode without resetting the current display. Use the buttons to enter the password, from left to right. With the Up button increases with one digit that is currently changing. With the Shift button, you move to the next digit to the left. The Clear button resets the entered password and re-enters the password. After entering the four digits of the password, it is confirmed with the Mode button and if it is correct enter the menus. Access password 1234. Depending on which key is going out of the operating mode and entering the password, it goes to the menus as follows:
– MODE: Initial setting level,
– SHIFT: Adjustment level,
– UP: Function setting level,
– CLEAR: Communications setting level.
If the password is incorrect, the display shows PASS ERR. If the Mode button is pressed, password is re-entered, and when Clear is pressed, it returns to working mode.
