1.10 Electrical system<br />
Refer to Figures 1-3 and 1-4 which show schematic diagrams of the electrical and control<br />
systems of the iH80, iH600 and iH1000 systems.<br />
1.10.1 Introduction<br />
Refer to Figures 1-3 and 1-4. The iH system has an Electrics Box (1), Electronics Module (3), a<br />
Gas Module (2) and a Pump Display Terminal (4). The iH1000 system also has an inverter<br />
(50). Optionally, your iH system may have an iH Interface Module, an iH Communications<br />
Module, an HCMB pump and other accessories, such as an exhaust temperature sensor (30)<br />
and a Pump Display Module (10).<br />
All of these Modules communicate through a serial data network. Each Module on the<br />
network has a microprocessor, which controls the network communications and also contains<br />
the default setpoints for the sensors in or connected to the Modules (see Section 2).<br />
1.10.2Electrics box<br />
Refer to Figures 1-3 and 1-4. The external electrical supply (5) is connected to the electrical<br />
supply connector (6) on the Electrics Box (1). The Electrics Box switches the electrical supplies<br />
to the HCDP pump and to the HCMB pump (on an iH600 system). The Electrics Box also<br />
provides the electrical supplies to the other Modules in the iH system. The electrical supply<br />
to the HCMB1000 pump in an iH1000 system is provided by the inverter (50).<br />
The Electrics Box has contactors for the HCDP pump and the HCMB pump (on an<br />
iH600/iH1000 system), pump power and current consumption sensors and short-circuit<br />
protection. The Electrics Box also has a transformer and fuses for the 24 V control circuits<br />
and fuses for the following supplies: iH Interface Module (11) and d.c. electrical supply (47).<br />
Three thermal-type, self-resetting fuses in the Electrics Box protect the d.c. electrical supplies<br />
to the network.<br />
Refer to Figure 1-5 detail D. The rear panel of the Electrics Box has the following lamp and<br />
connections:<br />
Power on lamp (7)<br />
Tool Interface Module<br />
connector (8)<br />
LON Interface Connector (9)<br />
Electrical supply connector (10)<br />
This lamp is on when the electrical supply to the<br />
Electrics Box is on.<br />
Use this to connect an iH Tool Interface Module to the iH<br />
system (see Section 8.5.3); or to connect an external<br />
emergency stop circuit to the iH system (see Section<br />
3.15); or to connect a Disconnect Box to the iH system<br />
(see Section 3.21).<br />
Use this to connect the iH system to a network.<br />
Use this to connect your external electrical supply to the<br />
iH system: refer to Section 3.16.3.<br />
