Description of the Device:
Shiva Amvaj time counter is a necessary device for industrial and home applications. By installing this time counter on your desired instrument, you can measure precisely the number of hours you have worked with that device. The recorded time is never erased from the time counter memory even after long power cuts.
The maximum measured time by Shiva Amvaj time counter is 99,999 hours (more than 11 years of nonstop working). Upon completion of this time, the system is automatically reset to zero.
Time Counter Features:
- High measuring accuracy
- Two display sizes for measuring hours and minutes
- Three indicators for announcing the following:
- T Indicator: Blinking: Total working time of the device (non-resettable)
Non-blinking: Working time measured after the last reset
- A: Set time for connecting the relay
- R: Time remaining before connecting the relay
- Adjustable time for connecting the relay
- Time-measuring function activated via connecting the START terminal to the phase
- Non-resettable total working time
- Measured time is stored in memory during power cut offs
- Supply voltage: 180-250 VAC / 50-60 Hz
- Maximum measured time: 99,999 hours (11 years)
- Measurement accuracy: 1 min
- Efficient operation range:
- Temperature: -20 deg C to +65 deg C
- Humidity: 70%
- Output: 5A relay
Upon placing Shiva Amvaj time counter in the desired location indoors, connect its phase and null terminals to those of the electricity grid. Then, connect the command circuit of the START terminal so that the START terminal would be activated each time the device or the system to be measured is switched on. The time measuring operation starts with the blinking of the point in the “minute” display upon switching on the system, and stops upon switching off the system and disconnection of the START circuit.
Shiva Amvaj time counter operates in three modes:
- During the NORMAL operation mode, the measured working time after the last RESET is displayed with the maximum measurement capacity being 99,999 hours (resettable after reaching the maximum limit). In this mode, the non-blinking T Indicator is ON and the lower display indicates the measured time in minutes.
- During NORMAL operation, by once pressing the UP or DOWN keys once, the T Indicator would start blinking and the time counter would display the total working time. This mode is non-resettable.
- In the third mode, the user can set an arbitrary time (anywhere between 1 min and 99,999 hours) upon the lapse of which the relay is connected automatically (see Page 7).
During NORMAL operation, by simultaneous depressing of UP and DOWN keys, you can observe the following parameters (in the same order):
- Non-blinking T Indicator: Measured working time (resettable)
- Blinking T Indicator: Total measured working time (non-resettable)
- Non-blinking A Indicator: User-set lapse time for connecting the relay
- Non-blinking R Indicator: Remaining time before the relay is connected
- Blinking R Indicator: Relay is being connected
Consecutive pressing of the ENTER key would lead to blinking of first the lower indicator and then the upper indicator numbers (from right to left). The desired numbers can be set by pressing the UP and DOWN keys. Press ENTER for confirming your selected numbers.
Resetting the Device:
- Resetting the relay connection time (RESET A): Upon setting the time for connecting the relay, the R Indicator light would start blinking. To reset the timer and restart of measuring, simultaneously press the UP and DOWN keys and hold them down at least 3 seconds. To disconnect the relay, press the ENETER key and hold it down for at least 10 seconds.
- Resetting the measured working time (RESET T): Holding down the UP and ENTER keys simultaneously for at least 3 seconds would start the count-down operation. Upon the lapse of the set time, the measured working time (from the last RESET) is automatically set to zero.
Note 6: To lock the device, press the ENTER and DOWN keys simultaneously and hold them down for at least 5 seconds. After the device has been locked, entering the initial set up mode is impossible. To unlock the device, again press the ENTER and DOWN keys and hold them down for at least 30 seconds.
Resetting the Device:
Upon reaching its timing limit, the device can be reset in two ways:
- Resetting via software: This is done by pressing the UP and DOWN keys and holding them down for at least 4 seconds. After this, the device can start measuring time from zero.
- Resetting via hardware: This is done by disconnecting and reconnecting the START input.
Upon selecting the desired subgroup, you can follow the procedures given below to set up the individual groups A, B, C, and D.
Group A Settings
As an example, we set up the device so that it would start operating 4 seconds after connection to the power supply. The required setting is as follows:
Reminder: Since we measure time in seconds, we first select A3 in the “Initial Settings”.
Press the ENTER key and wait for the indicator light (REAL) of the upper display to start blinking. Using the UP and DOWN keys, set the desired connection/disconnection delay time (4 sec in this example). Press the ENTER key again to save the set program and make the device ready for operation.
Group B Settings:
If Shiva Amvaj multi-timer is to be used for controlling the counterclockwise (ccw) or clockwise (cw) rotation of the motor in a specific device, then in the “initial Settings” Section, one of the subgroups of Group B must be selected.
The main settings are done after selecting Group B as explained below. For example, to set a motor to rotate in the ccw direction for 15 seconds, rest for 5 seconds, and then rotate in the cw direction for 10 seconds, we must follow the procedure described below:
Reminder: Since all the times (ccw, cw, and rest time) are measured in seconds, we must select B1 is the “Initial Settings” Section.
Press the ENTER key and wait for the upper display and the relevant indicator (REAL) to start blinking. Using the UP and DOWN keys, select the desired ccw operation time (15 sec in this example), and confirm your selection by pressing the ENTER key again. The Upper display and its indicator light (REL B) would start blinking again, indicating that the device is ready for setting the cw operation time.
Upon selecting the desired cw operation time (10 sec in this example), press the ENTER key to save your settings. Notice that the upper display and the REAL A and REL B indicators would again start blinking, thus indicating the device is ready for “rest time” adjustments (5 sec in this example). Upon setting the rest time, press ENTER to confirm your selection and exit the “Program Settings”. Now, the device is ready for the desired operation.
Group C and Group D Settings:
Group C settings enable the device to control the flasher ON/OFF times. For example, consider a water pump which pumps water for 1 hour and is then turned off for 4 hours. In this example, the time is measured in hours, and therefore, Group C3 must be selected in the “Initial Settings” Section. By pressing the ENTER key, the upper display and its indicator light (REAL) start blinking.
Using the UP and DOWN keys, select the desired operation time (ON) for the machine and press ENTER to confirm your selection. The upper display and the REL B indicator light would start blinking, indicating the device is ready for setting the OFF time. Enter the desired OFF time (4 hours) and press ENTER to save your settings.
Group D settings are similar to Group C settings, their only difference being the units used for measuring time.
Install the device inside the panel, or on any other surface (using the railing supplied in the box). You can use the Shiva Amvaj Panel Frame for mounting the device onto the panel.
Use the wiring drawing shown in the figure to wire the power supply, the start circuit, and the output terminals.
Note: For timing to start, the START terminal must be connected to the PH terminal.
