Start/Stop via Inp B.
counting while Inp B (Gate)
active (High level with
pnp; Low level with npn)
Count Start/Stop via INP B
(LOW-HIGH edge with
pnp; HIGH-LOW edge
with npn). Every active
edge changes the counter
status.
Count start via INP A,
stop via INP B. (LOW-
HIGH edge with pnp;
HIGH-LOW edge with
npn)

1. Description
• 6 digit time meter with SET/RESET function
• Red LED display, character height 8 mm
• Display range from 0 to 999 999
• Leading zeros suppression.
• Operation indicator: the decimal point of the
lowest digit blinks while the count is active.
• Programming via two setting keys on the front
side
• During programming, the display guides the
user with text prompts
• Time meter operating modes
– Counting while INP B is inactive (GAtE.Lo)
– Counting while INP B is active (GatE.hi)
– Count Start/Stop with INP B edge (Inb.Inb)
– Count Start with INP A edge, count Stop with
INP B edge (InA.Inb)
• Counting ranges h; min; s; h.min.s
• Optional optocoupler output
2. Inputs
INP A
Start input (depending on the input mode chosen)
INP B
Start/Stop or gate input (depending on the input
mode chosen)
SET/RESET input
Dynamic SET/RESET input. Linked in parallel to
the red RESET key. Resets the counter to the
predefined setting value.
3. Optocoupler output
(optional)
On active counting the output alternates at a fre-
quency of 1 Hz between active and inactive.
4. Programming routine
The programmable parameters of the device are
described below, in the order in which they can
be set. The device is fully programmed after one
pass of the routine.
The first values stated correspond to the factory
settings
