The Ecotel is not tted with a display terminal as standard. This is to prevent unauthorised access
to the controls software on units which can be targets for vandalism and are often installed at
remote and rarely attended locations. A pGD1 display is supplied loose with the unit as standard.
IMPORTANT
pGD1 Display
The units shall be supplied with a European ROHS Directive 2002/95/EC compatible microprocessor controller
connected to an 8 x 22 back-lit LCD keypad display. LEDs shall not be acceptable. The microprocessor controller offers
powerful analogue and digital control to meet a wide range of monitoring and control features including a real time clock
and industry standard communication port and network connections.
All the boards feature a 16 bit microprocessor, and consequently the calculation power and operation processing speed
have been signicantly increased. Also featured are a visual alarm and the facility to adjust and display control settings
by local operator for information and control.
