Jumpers are located on the lower half of the distribution board. The jumpers allow the engineer to
configure the outputs for either 24V switching or 0V switching at installation.
A label appears on the PCB indicating the correct jumper settings for each option:
Input – Allows the outputs to be configured as inputs in some
circumstances. Contact Status Scientific for further details.
Output (Switch 24V) – 0V always present at connector, 24V is
switched via a relay under processor control.
Output (Switch 0V) – 24V always present at connector, 0V is
switched via relay under processor control.
The label shown above indicates the correct positioning of
jumpers to obtain the specified output configuration.
It should be noted that the external outputs are not switched via voltage free contacts.
Depending on the configuration, either 24V or 0V will be permanently available at the
connector with the remaining supply being switched via a relay.
Under no circumstances must mains supply voltages be connected to any of the
distribution board terminals.
Pins 5 & 6 provide connection for an external switch.
1.4 Common Relay Module
Situated on the Relay Module are 4 Double Pole Change-Over Relays, each relay having
contacts rated at 8A (240V AC). Each of the relays can be configured as normally energised or
de-energised.
The standard configuration for these relays is
Any channel incurs a low alarm, common relay 1 will operate.
Any channel incurs a medium alarm, common relay 2 will operate.
Any channel incurs a high alarm, common relay 3 will operate.
RL4 is designated as a fault alarm relay.
These relays can be configured to provide alternative features via the software if required. Status
Scientific are able to implement modifications to the software to meet a customers specific
requirements, contact Status for further information.
