Timer
The software can be programmed to have the timer count up or down.
If the timer is used, the inputs have the following significance:
IN1: Start/Stop input
IN2: Reset input
IN3: Hold or Up/Down input
Output action after alarm is configurable. (*TN47, TVD1)

To attach the instrument, insert the two brackets in the housings on the top and bottom of the case and
tighten with the screws. To mount two or more instruments in a row or column, use the clips and respect
the following cut-out dimensions:
Row: Base (48 x n) -3, (1.89"x n) -0.11" Height 92 (+0.8/ -0) /3.62" (+0.03/ -0)
Column: Base 45 (+0.6/-0)1.77"(+0.02/-0) Height (96xn)-4/(3.78"xn)0.15"

where "n" is the number of instruments.
CE MaRkIng:The instrument conforms to the European Directives 2004/108/CE and 2006/95/CE with
reference to the generic standards: EN 61000-6-2 (immunity in industrial environment) EN 61000-6-3 (emission
in residential environment) EN 61010-1 (safety).

MaInTEnanCE: Repairs may be done only by trained and specialized personnel. Cut power to the instru-
ment before accessing internal parts. Do not clean the case with hydrocarbon-based solvents (trichloro-
ethylene, gasoline, etc.). The use of such solvents will compromise the instrument's mechanical reliability.
Use a clean cloth moistened with ethyl alcohol or water to clean external plastic parts.
TEChnICaL sERvICE: GEFRAN has a technical service department. Defects deriving from any use not
conforming to this manual are excluded from the warranty

For correct installation, follow the instructions and warnings contained in this manual.
Counter
The counter can be configured to count up or down.
A prescale factor (:2, :10, :100, x2) can be inserted on the Clock.
The displayed/set value can be expressed in engineering units.
Conversion (from number of pulses to engineering units) is done by
setting two factors (MUL and DIV), which will be multiplied or divided,
respectively, by the number of pulses actually counted.
The counter inputs perform the following functions:
IN1 : Clock input (fmax. 5KHz)
IN2 : Reset input
IN3 : Hold or Up/Down input
Output action is configurable. (*CN47, CVD)
Frequency meter
The inputs perform the following functions:
IN1 : Clock input
IN2 : Reset input for max. peak or min. peak functions
IN3 : Hold input
In this configuration as well, the display and setting can be expressed
as the value converted into engineering units by means of the MOL and
DIV factors. (*DRM)

utput funCtIOns
The output performs the following functions:
configuration as timer with countdown and input IN3 with HOLD (a) or
UP/DOWN (b) function.
In all other cases (counter and frequency meter), output functions are
unchanged.
In timer and counter mode, the max. trip delay is 1msec non-repetitive.
