4. OPTIONAL FUNCTIONS

The following optional functions are available by adding an optional board:

External Time Signal for Bell, Built-in Buzzer, and the Slave Clock.

External Time Signal and Built-in Buzzer

External time signal and Built-in buzzer shall be controlled by time table program and their duration settings.

Refer to the "18. SETTING THE TIME TABLE PROGRAM," and the "19. SETTING THE EXTERNAL TIME SIGNAL / BUILT-IN BUZZER."

Connection Specifications for External time signal contact

•Contact output: dry contact

•Contact capacity: 5A, 30VDC (Resistive)

The Slave Clock

The Slave Clock is a function to synchronize the time of the time recorder and the master clock. This function operates by choosing Slave Clock by Slave Clock setup.

Refer to the "20. SETTING THE SLAVE CLOCK."

Input signal Specifications.

•30-second reversal.

Since the 30-second signal (-V side) is not received, the difference from the master clock is 30 seconds or more, and the time is not modified correctly.

•60-second reversal.

Since the odd-numbered signal (-V side) is not received, the difference from the master clock is one minute or more, and the time is not modified correctly.

•59-minute impulse ( 2-wire )

From the 59th minute through the 49th minute the pulse is transmitted with line AB positive with respect to PC.

From the 50th minute to the 59th minute the pulse is transmitted with line AB negative with respect to PC.

During the 59th minute, the continuous pulse of 20 times is transmitted with line AB negative with respect to PC.

As this method monitors from 5 minutes before several preset hours to input 0-minute signal, more than 5 minutes of tolerance for a master clock can not compensate time correctly.
