Control Methods - Roberts Gorden CoRayVac CRV-B-2 Installation, Operation & Service Manual

! ! ! ! ! SECTION 12: Control Methods
There are several methods of controlling CORAYVAC
systems. The options are as follows:
1. ROBERTS GORDON
P/N 02770002
The System Control is an electronic control panel
designed to control CORAYVAC
System Control wiring is shown on Pages 45-46,
Figures 26-29 and in the System Control installation
manual P/N 10091601NA. The System Control can be
used to control an EP-100 or EP-201 pumps from the
control panel. Other pumps such as the EP-301 and 3
phase models may be controlled by a relay or motor
starter. The System Control can control up to four zones
of burners.
The electrical circuit is a 120V AC (20A) supply.
The output for the thermostat is 12V DC. Do not use
thermostats that draw power from the low voltage
supply.
A System Control operated system has two minutes
post purge pump operation to completely exhaust
products of combustion from the system and provides
indication of power to the pump, zones and indicates
the status of the vacuum proving switch with lights.
The System Control is UL listed in accordance with
UL873 – Temperature measurement and indicating
equipment.

in the ROBERTS GORDON
manual P/N 10071601NA. The ROBERTS GORDON
BZC700 can be used to control multiple CORAYVAC
systems consisting of five zones of burners and four
pumps.
The electrical circuit is a 120V AC (20A) supply.
Every control requires a ROBERTS GORDON
internal temperature sensor (P/N 10001500). The
sensors must be connected using a shielded cable
(Belden 8451 or equivalent).
The pumps cannot be connected directly to the
ROBERTS GORDON
relays, contactors or starters are required. Consult the
ROBERTS GORDON
more details.
The ROBERTS GORDON
have two minutes post purge pump operation to
completely exhaust products of combustion from the
system. The controls offer full energy management
features such as day and night temperature set points,
optimized start up and security coding. For full details
