Parameters Time Unit and Scale Selection Hour/Minute It can be adjusted from to Minute/Second It can be adjusted from to Second/Milisecond It can be adjusted from to Hour/Minute It can be adjusted from to Hour It can be adjusted from to Minute It can be adjusted from to Second It can be adjusted from to Filter Time of Reset, Pause and Start Inputs It is used to protect against the electrical contact debounce or the signal that is less than the determined pulse time.
Output Functions Manual Reset-1. Device continues to count till manual reset is applied. (Output PulseTime is not considered) Count direction : 0 --> P (Upcounting) = Start Reset Set 0 Output = = Or When count value reaches the Set Value, Output Position is changed. Counting process continues over the SET value. Output Pulse Time is not considered. Process counts, until manual reset happens. Counting is continues, while Start input is active. When Start input is passive, count value becomes “0”.
Manual Reset-2. Device continues to count till manual reset is applied. (Output pulse Time is not considered) Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 Output = = Or When count value reaches the Set Value, Output Position is changed. Counting process is not continue over the SET value. Output Pulse Time is not considered. Process counts, until manual reset happens. When Manual Reset happens, count value becomes 0 value. Counting is continues, while Start input is active.
Manual Reset-3. Device continues to count till manual reset is applied. (Output Pulse Time is considered.) Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 Output = Output = When count value reaches the Set Value, Output Position is changed. If Output Pulse time is not 0, then Output = Position is changed at the end of the Pulse time. If then Output Position has not change, until Manual Reset happens. Counting process continues over the SET value.
Automatic Reset-1 Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 Output = Output = When count value reaches the Set Value, Output Position is changed. Actual value is reset automatically. While Start input is active, then counting starts upcounting from 0 value. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time. If , then Output Position has not changed until = Manuel Reset happens. When Manual Reset happens, count value becomes 0 value.
Automatic Reset-2 Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 = Output Start Reset Set 0 Output = When count value reaches the Set Value, Output Position is changed. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time and Actual value is reset and if the Start input is active, then counting starts from 0 value. If output pulse time is “0”, then output position has not change until Manual Reset happens.
Counting direction : P --> 0 (Downcounting) = Start Reset Set 0 Output = Start Reset Set 0 Output = When count value reaches the 0 Value, Output Position is changed. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time and Actual value is reset. If the Start input is active, then counting starts from Set value. If output pulse time is 0, then output position has not change until Manual Reset happens. Actual counting value stops at 0 value.
Automatic Reset-3 Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 = Output Start Reset Set 0 = Output When count value reaches the Set Value, Output Position is changed. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time and Real counting value is shown on Actual = value screen. If output pulse time then, output position has not change until Manual Reset happens.
Counting direction : P --> 0 (Downcounting) = Start Reset Set 0 Output = Start Reset Set 0 Output = When count value reaches the 0 Value, Output Position is changed. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time and Real counting value is shown on Actual = value screen. If output pulse time , then output position has not change until Manual Reset happens.
Automatic Reset-4 Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 = Output Start Reset Set 0 Output = When count value reaches the Set Value, Output Position is changed. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time and counting value becomes 0 and output becomes inactive position. If output pulse time ,then = output position has not change until Manual Reset happens.
Counting direction : P --> 0 (Downcounting) = Start Reset Set 0 Output = Start Reset Set 0 Output = When count value reaches the 0 Value, Output Position is changed. If Output Pulse time is not 0, then Output Position is changed at the end of the Pulse time and counting value becomes Set value and = output becomes inactive position. If output pulse time , then output position has not change until Manual Reset happens. When counting value reach 0 value, output position becomes active position.
Automatic Reset-5 is not considered. Counting direction : 0 --> P (Upcounting) = Start Reset Set 0 Output = = Or If the Start input is active, then Process starts counting, until count value reach SET value. When count value reach SET value, Output Position becomes active position and process is automatically reset. If the Start input is active, then process start counting from “0” value. If count value reach SET value, Output Position becomes passive position.
Output Run Type Output Normally non-energised Output Normally energised Output Pulse Time It determines how long Output will be active. It can be adjusted from 00.00.00 to 99.59.99 (99 minutes; 59.99 seconds). For details, refer to the section where output functions are defined Direction of Counting Upcount. ( 0 --> Preset ) Downcount. ( Preset --> 0 ) Data Record Count value is saved to memory when power is disconnected and restored on power up.
Program Password It is used for accessing to the program parameters. It can be adjusted from to . If it is , there is no password protection while accessing to the parameters. When programming button is pressed, will appear on the display. If program password is not “0” while accessing to the program parameters ; 1- If user does not enter the value correctly ; operation screen will appear without entering to operator parameters.
6. Failure Messages in EZM-7735 Programmable Timer 1-If the password is not 0, user can access to the parameters without entering the password and by pressing ENTER button. User can see all parameters except for programming password parameter but user can not do any changes in parameters. If password is entered for accessing to the parameters correctly, most significant digit of the parameter flashes. But if the password is not entered, flashing of the most significant digit is not realised.
