Setting up the summary alarm module
Your summary alarm module is delivered fully configured and ready to work. Below are details of how to change from these default
configurations
Default configuration
The module is delivered with the following configuration.
ALARM MASKING
AUTOMATIC
MANUAL MASK
all slots OFF
LOAD switches
all OFF
Setting the Alarm masking, manual mode
Details of the DIP switch positions are given in section 2.4.1. If you wish to configure your module to have alarms manually masked follow
the sequence below. Any masked slot will have its alarm output ignored. Unpopulated slots will generate alarms, therefore these should be
masked. DIP switches can be accessed with the module partially withdrawn.
1.
Set SW3 position 1 to OFF, this configures the module for manual alarm masking
2.
Each slot that you wish to mask the alarm of be should be set to OFF, using DIP switches SW2 and SW3
3.
Each slot that you wish to monitor should be set to ON, using DIP switches SW2 and SW3
Setting the Alarm masking, automatic mode
Details of the DIP switch positions are given in section 2.4.1. If you wish to configure your module to have alarms automatically masked
follow the sequence below. Any masked slot will have its alarm output ignored. DIP switches can be accessed with the module partially
withdrawn.
1.
Set SW3 position 1 to ON, this configures the module for manual alarm masking
2.
Set all other DIP switches of SW2 and SW3 to OFF
Unpopulated slots will not respond to the I2C pole therefore these will all be masked. When in automatic mode, manual alarm masking DIP
switches (SW2 positions 1-8, SW3 positions 2-8) are ignored
Setting the load DIP switches
Detail of the DIP switch positions are given in section 2.4.2. If you wish to activate any of the resistive loads follow the sequence below.
DIP switches can be accessed with the module partially withdrawn.
1.
Calculate the additional load required, see section 2.4.2.
2.
Round this load up to the nearest three watt step
3.
Switch the appropriate number of DIP switches of SW5 to the ON position
Note. If sufficient load is not applied, it is possible for a PSU front panel power LED to be
GREEN
and the “power good” output to be LOW
(alarm state), in this case the power supply will not be registered by the
ViaLiteHD
control cards.
Connecting to the rear relay connections
The pin out of the rear 6 way connector is given in section 2.3.1. The connector can be used with wire gauges 14
– 22 AWG.
To insert a wire follow the sequence below.
1.
Strip the wire leaving approximately 10mm of exposed copper
2.
Tightly twist all strands together
3.
Push the latch at the top of the connector back with a small flat bladed screw driver
4.
With the latch held in, insert the wire
5.
Push the wire home then release the catch
To release a wire follow the sequence below.
1.
Push the latch at the top of the connector back with a small flat bladed screw driver
2.
With the latch held in, pull the wire from the connector
3.
Release the catch
