Appendix 4.15    Setting counters externally 

With an external digital switch having 4 digits, a counter can be set remotely and 

their current values are displayed in 4 digits. In addition to every count-up, the timer 

outputs data when it reaches a value 100 short of the set value and a value 50 short 

of the set value. 

Note that a setting error is indicated if the set value of the counter is less than 100.
