Setting and parameterization
To set the parameters, the device has the four pushbuttons Esc, CR, and . Parameterization
can be canceled using the Esc button. Set parameters are retained even after the operating
voltage has been switched off.
Start parameterizing mode: Press Esc.
Using the buttons and , select the required main menu.
Open the required main menu: Press the CR button.
Using the buttons and , select the required submenu.
Open the required submenu: Press the CR button.
Using the buttons and , select the required value.
Save the required value: Press the CR button.

Main menu — input parameters
ICM… Input circuit monitoring: When using NAMUR sensors, input circuit monitoring
can be activated. In the event of an error, the relay outputs drop out, the transis-
tor is inhibited and the analog output goes into fault current mode.
ICMOf No monitoring
ICMBS Wire break and short-circuit detection
ICMB Wire break detection only
ICMS Short-circuit detection only
Tb Time base: Standard setting: 1 = Hz
If a different unit is required, enter the corresponding factor for the conversion.
The value 60 applies to the conversion of Hz to rpm. The measured rotational
speed in Hz is multiplied with the factor (Tb). Carry out the following switching
threshold settings in the unit specified here.
TbUnit Unit — time base: It depends on the time base factor (Tb). Hz is displayed as
the unit for the factor Tb = 1, and rpm (revolutions per minute) as the unit for
Tb = 60 rpm. Three freely selectable characters for the unit can be set if Tb is not
equal to 1 or 60.
NoTar Number of damping elements: Number of elements that damp the sensor per
revolution of a shaft. The measured speed is divided by the number of damping
elements (NoTar).
Tc Time constant of the filter in seconds to avoid superimposed interfering
frequencies (fig.3).
Td Input lock-out time in seconds: After a pulse from the sensor, the sensor input
will not be scanned for the set time (0…99.9 s). Therefore, faults, such as those
caused by bouncing, can be suppressed with slow input pulse trains. An exact
knowledge of the input pulse trains is required for the setting.
F-0 Zero detection: If the speed falls below the value set here, the input frequency
will be output as zero.
AOut
(See g. 6)
Main Menu — Analog Outputs
I-Out Submenu I — Current Output (g. 3)
F-IL Setting of the frequency (start of the measuring range) for an output current of
0 or 4 mA. Where the measuring range is undershot, the current falls linearly to
3.8mA if an output current range of 4…20mA is selected.
F-IH Setting of the frequency (measuring range end) for an output current of 20mA.
Where the measuring range is overshot, the current increases linearly to 20.5
mA.
If F-IL > F-IH, the characteristic curve has an inverse trend: 20…4/0 mA
0/4 mA Output current range: 4.000 (4…20 mA), 0.000 (0…20 mA)
I-Err Fault current in the event of a wire break or short circuit (NAMUR sensor only
when monitoring activated) and detected error on the device
22.00 > 22 mA
0.000 0 mA

2-Spt Submenu II — 2-Point Operation
The 2-point switching operation is used to monitor the underspeed (0 < Off < On) or over-
speed (0 < On < Off). In the submenu of "2-Spt," the "On" and "Off" functions are used to
determine the switching and tripping points.
Off Tripping point in 2-point operation for monitoring undershoot or overshoot.
On Switching point in 2-point operation for monitoring undershoot or overshoot.
SUD Start-up bypass time in seconds: After the start-up bypass has been activated,
the output parameterized to undershoot is compulsorily activated for the set
time and the reporting of underspeed is prevented during the startup phase.
The start-up bypass is started either by short-circuiting terminals 9 or 10 or by
creating the operating voltage.
DSOn Dynamic start-up bypass: The start-up bypass time is canceled immediately as
soon as the measured speed has overshot the set limit values for the under-
shoot.
DSOf Expiration of the start-up bypass without cancel option: Undershoot monitor-
ing does not take place until the start-up bypass time (SUD) has expired.
TOff Switch-off delay in seconds: A speed that leads to a relay shut-off must exist
continuously for the set time (0…999.9 s). Thus, short-term speed fluctuations
cannot trigger a message.
LocOf No locking
LocOn Locking of the relay: After the corresponding output has been switched off, it
remains in a dropped-out state until either terminals 9 or 10 are short-circuited,
the operating voltage is reapplied or the CR button is pressed.
4-Spt
4-Spt-Inv
Submenu II — 4-Point Operation
4-point switching operation is designed for monitoring a window function. The "U-off," "U-on,"
"O-on" and "O-off" functions are available in the submenu of "4-Spt" for the respective switch
points (fig. 3). An inverted window function can be set in the submenu "4-Spt-Inv."
The following switching/tripping points must be entered with an increasing numerical value:
4-Spt: (U-off < U-on < O-on < O-off)
4-Spt-Inv (U-on < U-off < O-off < O-on)
U-off 4-Spt: Tripping point for speed undershoot: If the speed drops below the set
value, the relay drops out.
4-Spt-Inv: Tripping point for speed overshoot: If the speed increases above the
set value, the relay drops out.
U-on 4-Spt: Switching point for speed undershoot: If the speed increases above the
set value, the relay drops out (U-On < O-on).
4-Spt-Inv: Switching point for speed overshoot:
If the speed drops below the set value, the relay is energized.
O-on 4-Spt: Switching point for speed overshoot: If the speed drops below the set
value, the relay is energized.
4-Spt-Inv: Switching point for speed undershoot: If the speed increases above
the set value, the relay is energized.
O-off 4-Spt: Tripping point for speed overshoot: If the speed increases above the set
value, the relay drops out.
4-Spt-Inv: Tripping point for speed undershoot: If the speed drops below the set
value, the relay drops out.
SUD Start-up bypass time in seconds: After the start-up bypass has been activated,
the output parameterized to undershoot or window function is compulsorily
activated for the set time and reporting of underspeed is prevented during the
start-up phase. The start-up bypass is started either by short-circuiting termi-
nals 9 or 10, or by creating the operating voltage.
DSOn Dynamic start-up bypass: The start-up bypass time is canceled immediately as
soon as the measured speed has overshot the set limit values for the under-
shoot.
DSOf Expiration of the start-up bypass without cancel option: Undershoot monitor-
ing does not take place until the start-up bypass time (SUD) has expired.
TOff Switch-off delay in seconds: A speed that leads to a relay shut-off must exist
continuously for the set time (0…999.9 s). Thus, short-term speed fluctuations
cannot trigger a message.
LocOf No locking
LocOn Locking of the relay: After the corresponding output has been switched off, it
remains in a dropped-out state until either terminals 9 or 10 are short-circuited,
the operating voltage is reapplied or the CR button is pressed.
Alarm Submenu II — Operation as Alarm Output
PDiv Submenu II — Operation as Pulse Divider
Div In the submenu "PDiv," a value is set for the part ratio (only possible for a tran-
sistor output). Factor for signal division of the input frequency: Example: Div
= 2. With every other pulse, the transistor switches with the rising edge of the
input and retains the switching state until the next rising edge.
