2.9.2

Normally De-Energised Relays

A relay set to be ‘ND’, will, under normal (non-alarm) conditions, have no power applied to its coil. With no power

applied to the coil, the ‘Common’ relay terminal will be connected to the ‘NC’ terminal (as marked on the terminal

label).

When an alarm state exists that is configured to drive an ‘ND’ relay, power is switched to the coil and the contacts

change state. The ‘Common’ relay terminal will now be connected to the ‘NO’ terminal. The changing state of the

contact signals an alarm condition.

If the Controller is operating with no active alarm conditions, all relays set to ‘ND’ will be unpowered and inactive. If,

during this condition, power is removed from the Controller, there will be no change of state of any of the relay

contacts. Relays set to ‘ND’ cannot signal a fault condition due to power loss. Although the state of the relay

contacts is ‘preserved’ (i.e. not changed) under non-powered conditions, this is not an intentional state preservation,

rather it is just an outcome of having normally inactive (unpowered) relays.

2.9.3

Normally Energised Relays

If it is required to signal a fault due to power loss, relays should be configured to ‘Normally Energised – NE’

operation.

Relays set to ‘NE’ will have power applied to their coils during the normal (non-alarm) state. Under these conditions,

the ‘Common’ relay terminal will be connected to the ‘NO’ terminal (as marked on the terminal label). For ‘NE’

configured relays, the function of the contacts, as marked on the terminal label, is reversed (i.e. ‘NO’ becomes ‘NC’

and vice versa).

When an alarm state exists that is configured to drive an ‘NE’ relay, power is removed from the coil and the contacts

change state. The ‘Common’ relay terminal will now be connected to the ‘NC’ terminal (as marked on the terminal

label). The changing state of the contact signals an alarm condition.

If the Controller is operating with no active alarm conditions, all relays set to ‘NE’ will be powered. If, during this

condition, power is removed from the Controller, there will be a change of state of any of the relay contacts since the

coils are no longer being supplied with power. Relays set to ‘NE’ are therefore able to signal a fault condition due to

power loss.

2.9.4

Alarm Set-Point Delays

Under some conditions, it may be desirable to trigger a set-point, only if an alarm condition has existed greater than a

certain period of time. This allows transient conditions to occur without triggering an alarm event.

The Controller allows a delay to be set from 0 – 9999mS (9.999 seconds). The delay is common to all 5 trip-points

within a channel but each channel may have a different delay.

When setting alarm set-point delays, it is important to ensure that the time set before a relay is

triggered, does not create a hazardous situation. Delays must set based on an understanding of

their effect on the system into which the controller is fitted.
