3.6.2 Dryer Supply
If a Parker domnick hunter pre-treatment air dryer is used, it should be connected to the generator at the dedicated DIN rail terminals. Refer the
documentation provided with your dryer for additional information on installation requirements.
3.6.3 Purge Economy
If the pre-treatment dryer is fitted with a purge economy feature, it may be controlled using the volt free relay contacts on JP17. The relay is
energised only when the generator enters standby mode. Refer to the documentation provided with your dryer for details on purge economy.
3.6.4 Alarm Contacts
Each generator is fitted with a set of volt free relay contacts designed for remote alarm indication and are rated 1A max @ 250Vac (1A @ 30Vdc).
Under normal operation the relay will be energised and the alarm circuit will be open. When a fault occurs, e.g. power failure, the relay will de-
energise causing the alarm circuit to be complete.
3.6.5 Remote Switching
The generator may be controlled remotely by connecting a remote start / stop circuit to digital input #4 on the control board. When the circuit is
open the generator should remain in standby mode, closing the circuit should initiate a start command.
To enable the remote switching function refer to 4.4.3 of this guide. Once the remote switching function has been enabled the local start control
will no longer function.
