3.4 Example 4: Several appliances control several auxiliary devices (extreme situation)
Example: Building with several apartments, each with one oven, range hood and motor flap, and with one roof ventilation fan
per building.
Control function - When an oven or range hood is switched on, the corresponding motor flap opens.
- When any motor flap opens, the roof ventilation fan is switched on.
Notes / Limitations
1) In the case of SSM2, either just one or both current sensors can be used. The sensors are to be in-
serted into those pole conductors whose current flow is crucial to controlling the auxiliary device. If
the internal wiring of the connected appliance is unknown, the relevant pole conductors must be de-
termined through testing.
In the case of appliances with a connection with only two pole conductors and no neutral conductor
(connection type 400V2~), a current sensor is to be inserted in one of either pole conductors (up to
16A, it is possible to use SSM1).
2) The number of all sensors connected in series may not be greater than six. In the case of SSM2, if
both sensors are used this counts as two units.
3) If several auxiliary devices are to be controlled and these are in different fuse groups, then several
relay modules are to be used. The output signal of the first relay module can be relayed to the input
terminals of a maximum of six other modules (see above for connection).
As an alternative, a sensor signal can also be sent in parallel to a maximum of two relay modules
(switch inputs 1-2 of the relay module in parallel).
4) If several appliances, i.e. several sensor modules, are to control an auxiliary device, then the out-
puts of all associated sensor modules are to be switched in series with correct polarity.
Because of generally unknown phase shifts between the individual pole conductors, the accuracy of
the polarity can only be determined by testing. To function correctly, the control signal voltage,
measured by the relay module, must increase whenever the current increases in any one of the sen-
sors concerned.
Recommended function test after all modules are connected:
Note: Values in (..
) = valid for relay module version P60.010-1, delivered up until around September 2005
1. Allow an approximately 0.11A~ (0.25A~)
current to flow through the first sensor and leave switched on
throughout the entire test sequence (e.g. connect 25W light bulb (60W)
). Leave all other sensors without
current.
2. On the relay module, connect a volt meter to terminals 3-4 (to measure the amplified sensor signal).
Check whether the voltage is at 1.3V~ ±0.3V.
3. Additionally, in the case of any other sensor allow roughly the same current to flow through as with the first
sensor (e.g. connect second light bulb 25W (60W)
).
Check that the voltage reading on the voltmeter is at least 50% higher.
If this is not the case, change over the connection wires on terminals 1-2 of the relevant sensor.
After a successful test has been performed, switch off the current in this sensor again.
4. Repeat point 3 for all other sensors concerned.
