ULTI TAGE UNNEL
When in static pressure mode and employing multiple tunnel curtains, Platinum Touch/Rotem One Touch
can open the curtains in sequence. Opening the tunnel curtains commences when the target static
pressure is reached and the controller signals to the tunnel machine to operate the curtains. Platinum
Touch/Rotem One Touch opens the first tunnel curtain (as defined in the relays) to the user defined
level. If additional ventilation is required, the second tunnel curtain opens. This process continues for
each defined curtain.
As pressure falls, the process is reversed; curtains close in progression starting with the last curtain.
To set up Multi Stage Tunnel Curtains:
1. In System > Relay Layout
2. In System > Levels of Ventilation > Vent & Curtain Levels, define the opening levels for each curtain.
3. In Static Pressure > Tunnel Ventilation, define the target pressure.

3.8 Cool Pad

This menu sets the cool pad operating conditions.
NOTE Cool Pads only operate when the controller is in tunnel mode. For example, if the cool pad is
set to run at Level 8 and the tunnel mode begins at level 10, the cool pad remains inoperative.
1. In System > Relay Layout, define relays as Cool Pad.
2. Go to Control > Cool Pad.
