SELECTING THE H7EC TOTALIZING COUNTER
Determine the maximum counting speed of the counter by
evaluating the input conditions listed in the table at right.
Counting speed
Contact
signal input
20 or 30 cps
Relay or switch
contact input with
some chattering
1 kcps
Do not input contact
signal inputs.
Chattering is counted
as signal input.
High-speed transistor
inputs
Solid-state
signal input
Low-speed
transistor inputs

MANUALLY RESETTING COUNTERS
(-M SUFFIX MODELS)
Counters with "-M" suffixes offer the option of manual or external
resetting. To manually reset the counter, press the reset button
located to the left of the display window. To prevent an accidental
reset, lock the reset button by sliding the button downward, without
depressing it. A small "click" sound may be heard, both when
locking and unlocking the reset button. Slide the button up to
unlock.
