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)

• Dimensions and cut-out; panel mounting
Panel mounting.
Faceplate dimensions: 48x48mm./1.89"x1.89" (1/16DIN); depth: 100mm/3.94"
Cut-out dimension: 45(+0.6/-0)x45(+0.6/-0)mm/1.77" (+0.02/ -0)x1.77"(+0.02/-0)".

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: EMC (electromagnetic compatibility) conformity to EEC Directive 89/336 with reference to
generic standards EN50082-2 (immunity in industrial environment) and EN50081-1 (emission in residential
environment).
45
BT (low voltage) conformity to EEC Directive 73/23 modified by Directive 93/68.
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 (trichloroeth-
ylene, 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

2 • TECHNICAL DATA
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 set-
ting 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)

O
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.
