Digital Timer/Counter ENS20

Operating Instructions
English translation
Errors and technical changes reserved
The following function settings are valid depending on the
value of the function 2 for
timer mode (2-0 to 2-6)
or
counter mode (2-7).
ENS20 as timer (2-0 to 2-6, see function 2)
Timing begins with turning on the starting signal (1-3) and
can be interrupted by this input as desired. The START
input 1-3 can be closed by a cable link. In this case timing
begins directly with switching on the mains voltage. RESET
and START input have an internal noise pulse suppression.
They may be activated by contacts or electronic initiators.
ENS20 as counter (2-7, see function 2)
All functions 3 to 8 also apply to the counter mode. The
clock input is provided at the terminals 3 (+12..24 V) and 1
(0 V). Counting is done by closing an external counting
contact. Also 2- or 3-wire semiconductor outputs of initia-
tors can be used. The falling edge is counted.

Function 3:
Timing functions
3– 0
On-delay.
Timing begins with applying of
the mains voltage and closing of the
START-contact. After timing the contacts
switch from 15-16 to 15-18 until the arrival
of a resetting signal, at least however for
100 ms.
3 – 1
Impulse-limiting.
As On
-
delay, however
the contacts are switched on with applicati-
on of the mains voltage immediately (15-
18) and back to 15
-
16 after timing.
3 – 2
Flashing (T1=T2).
The ENS20 works after
applying of the mains voltage and closing
of the START contact as symmetrical cyc-
ling timer. The cycle starts with output off
(relay switched off). On and off time are
equal.
3 – 3
Flashing (T2=100ms).
In this operating
condition the output relay switches periodi-
cally for 100ms. The total cycle time is de-
termined by the preselected current value.
3 – 4
Signal off-delay.
The control is made by
the START contact. The contacts switch on
immediately and after opening the starting
contact timing begins. After timing the
contacts switch back to 15-16. A stop is not
possible here.

Function 4:
Counting direction
4 – 0
upward.
Timing/counting begins with zero
and ends with the preselected value. A
RESET signal sets back to zero.
4 – 1
downward.
Timing begins with the presel-
ected value and ends with zero. A RESET
signal sets back to the preselected value.
Display
Function 5:
Power failure function
5 – 0
Continuation.
Timing is continued after
power failure with the value reached last.
5 – 1
Restart.
Timing begins after power failure
with zero or with the preselected value
(RESET after power failure).
Display
Function 6:
Enable/disable programming
6 – 0
Programming enabled during timing.
Programming during timing (i.e. the START
signal is turned on) is enabled. Timing is
stopped and continued after the recent
time preselection with the new values.
6 – 1
Programming disabled during timing.
The programming mode by "

keys is not possible during timing (i.e. the
START signal is turned on). Programming
only, if the START input is turned off.

Function 7:
Aux. contact, only version 52311x
7 – 0
Auxiliary contact is immediate contact.
Timer mode: The 2nd contact switches
with applying the START signal .
Counter mode: The 2nd contact switches
on with the first counting pulse.

Auxiliary contact is progammable pre-
contact
The display shows next
"Pxx ".
xx is the timer/counter value of the 2nd
contact. Set the value with
<, >
e.g.
"P52".
Through this the 2nd contact switches on
52 clocks before reaching the timer/counter
preselection (1st contact). With the value
"P00 "
the 2nd contact switches at the
same time as the 1st contact with reaching
the preselection value.
