1 • INSTALLATION
• Dimensions and cut-out
Panel mounting.
Front panel dimensions: 96x48mm./3.78"x1.89" (1/8DIN); depth:152mm /5.98"
Cut-out dimensions: 92 (+0.8/-0)x45 (+0.6/0)mm/3.62" (+0.03/-0)x1.77" (+0.02/-0)".
To lock the instrument, insert the two blocks into the dovetail guides (split), diagonally
115
(vertically) to one another and tighten with the screws. To install two or more
instruments side by side or stacked, use the locking blocks and the following hole
measurements:
side by side - Base (96 x n)-4 / (3.78 x n)-0.15" Height 45 (+0.6/-0) / 1.77" (+0.02/-0)
70
column - Base 92 (+0.8/-0) / 3.62" (+0.03/-0) Height (48 x n)-3 / (1.89" x n)-0.11"
where "n" is the number of instruments.

CE MARKING: EMC (electromagnetic compatibility) conformity to EEC Directive 89/336
with reference to generic standards EN61000-6-2 (immunity in industrial environment)
and EN50081-1 (emission in residential environment).
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 instrument before accessing internal parts. Do not clean the case with
hydrocarbon-based solvents (trichloroethylene, 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.

3 (10) alarm setpoints settable in absolute value with functions
completely configurable from panel keys
(Direct / Reverse / Relative / Symmetrical relative)
- Setting of setpoint along entire selected scale.
- Trip hysteresis settable from panel keys.
- Function: minimum or maximum trip points with saving of trip (LATCH)
selectable during configuration.
Relays energized or de-energized in trip status: selected from panel
keys.
Trip can be excluded during power-up phase until input variable
exceeds set trip point.
Relay trips when variable drops below trip point. Output activation can
be timed.
Trip response time:
for Out1 ... Out 2 = 2msec
for Out 3 ... Out 10 = 8msec
