INSTRUCTIONS
IMPORTANT: Read these
instructions before installation
and wiring of the product.
Electronic rotation sentinel
SPINN/D is an electronic rotation sentinel, primarily intended for
supervision of rotating heat exchanger wheels. It has a single pole
change-over alarm relay and provisions for blocking the alarm out-
put at intentional stops.
SPINN/D is to be used with the RR-G3 sensor. SPINN/D is built for
DIN-rail mounting and has all settings accessible on the front.
Installation
Mount the electronics unit on a DIN-rail in a cabinet or other enclo-
sure.
Protection class:
IP20
Ambient temp:
0 - 50°C
Fasten the supplied magnet to the wheel’s mantle surface. Mount
the sensor in line with the magnet and with an airgap of less than
10mm.
Protection class:
IP65
Ambient temp:
-20 - +70°C
Wiring
Supply voltage and output
Supply voltage: 230V AC +/-15% 50 - 60Hz
Connect the supply voltage to terminals
1 and 2.
Output: SPDT relay 5A 230V AC
Terminal 4 = Common pole
Terminal 5 = Normally open
Terminal 6 = Normally closed
Sensor
Connect the sensor RR-G3 to terminals 9 and 10. The sensor is not
polarized.
Logic input
Terminal 7 = signal neutral
Terminal 8 = 0 - 20V DC or phasecut
Switch
With the TEST/RUN switch two different alarm-delay times can be
set.
TEST = 20 sec.
Used for function testing.
RUN = 3 min.
Used for normal operation.
Logic function
The logic function is primarily intended for applications with
variable speed wheels.
A 0 - 20V DC control signal can be applied to the logic input. If
the signal is lowered below 4V the alarm relay is held in run-
ning mode even if the rotational speed falls below the alarm
threshold. In other words, SPINN/D will not give an alarm at an
intentional shutdown of the wheel, only unintentional stops due
to for example the drive-belt breaking.
Should the belt break when SPINN/D is in blocked mode (control
voltage <4V) the speed controller will eventually call for hig-
her speed and will then raise the control signal above 4V and
SPINN/D will give an alarm. By connecting the logic input to a
potential free contact in the motor contactor SPINN/D may be
blocked even when using on/off control. The contact should
close when the motor is stopped.
N.B. Leave the input open if the function is not used.
Startup
Set the switch to the TEST position. Turn the wheel so that the
magnet is not opposite the sensor. Disconnect the wiring, if any,
to the logic input. Connect the supply voltage to SPINN/D but
don’t start the wheel. Only the red LED should be lit and the
relay should be in running position. After approx. 20 sec. the red
LED should light up and the relay switch to alarm position. Turn
the wheel so that the magnet is opposite the sensor. The green
LED should go out. If not, check the sensor wiring and the gap
between sensor and magnet.
When everything is OK, set the switch to the RUN position, start
the wheel and let it run at normal speed. When the magnet has
passed the sensor twice the red LED should go out and the
alarm relay is reset. The green LED should wink every time the
magnet passes the sensor.
Reconnect the wiring, if any, to the logic input, stop the wheel
and check that no alarm is given after the end of the normal
delay time (3 minutes).
