GVI-002 – Gas Valve Interlock Control Panel – Cadamp

GVI-002 – Gas Valve Interlock Control Panel – Cadamp

Installation
1. Install in a dry sheltered position. Do not install in close proximity to a heat source.
2. All wiring and control equipment MUST comply with current applicable regulations.

Operation
The GVI-002 is a gas interlock control system that can be used with either pressure switches or current sensors to monitor fans and enable the electrical supply to a gas valve solenoid.

Pressure switch use
GVI-002 has connections for 2 pressure switches. These pressure switches are to be wired to the panel
using the normally open contacts, which close when there is airflow present. When airflow is proved the airflow on lamp will light and the electrical supply to the gas valve solenoid will be enabled, the gas on lamp will light. When there is a loss of airflow the gas valve solenoid will remain enabled for 10 seconds. This is to prevent loss of gas in the event of backdrafts.

Current sensor use
The GVI-002 has connections for 2 current sensors. When fan current flow is proved the airflow on lamp will light and the electrical supply to the gas valve solenoid will be enabled, the gas on lamp will light. When there is a loss of fan current the gas valve solenoid will remain enabled for 10 seconds. This is to prevent loss of gas in the event of backdrafts.
Remote emergency stop button connections
The GVI-002 has connections to allow the fitting of a remote emergency stop button if required.

Commissioning jumper lead.
GVI-002 has a (blue) commissioning jumper lead. Fit this jumper lead into the socket provided to enable the electrical supply to the gas valve solenoid for test/commissioning purposes only.
