3.3.1.6. Connecting the External Valve Driver Option

42
Any of six external valve driver assemblies, 12V or 24V (options listed in Table 3-6),
are available that can drive up to eight 8-watt valves based on the condition of the status
block bits described below. The option consists of a custom Printed Circuit Assembly
(PCA) that mounts to the back of the T700 with or without a universal AC-to-DC power
supply module (PSM).
The Valve Driver Outputs are mapped one-for-one to the Control Outputs 1 through 8
and can be manually actuated for troubleshooting using the Signal-I/O diagnostic
function in the T700 software (see Section 9.4.11.5). However, the drive outputs are
mapped in reverse to the status control bits such that Bit-0 (LSB) is valve drive 8 and
Bit-7 is valve drive 1.
