7.4.4 Pump-to-controller cables
You must fit a pump-to-controller cable between an EXC Controller and the EXT Split Flow Pump. A
cable is not supplied with the EXT Split Flow Pump or the EXC Controller (except EXC100L). The
following cables are available:
7.4.5 EXT Water cooling block assembly
A water-cooler can be fitted to the EXT Split Flow Pump. However please refer to Section 2.4 to check
the stability of the cooling-water supply.
7.4.6 TAV Vent-valve and vent-port adaptor
Two solenoid-operated vent-valves are available for system venting. The valves are 24 V d.c., normally-
open, and can be driven automatically from the EXC Controller. The solenoid-valve is fitted in place of
the manual-valve, or alternatively can be fitted with an adaptor (supplied with the valve) and be used with
any suitable NW10 flanged port on your vacuum system. The vent-port adaptor allows the vent-port or
the purge-port to be used with any suitable NW10 fitting.
7.4.7 ACX Air-Cooler
An ACX air-cooler can be fitted to the EXT Split Flow Pump. However, please refer to Section 2 to
check the suitability of air-cooling in a particular application.
