ADDITIONAL INFORMATION
RS-485 COMMUNICATIONS
RS-485 is a US-based telecommunications standard for binary
serial communications between devices. It is the protocol, or
set of specifications, that needs to be followed to allow devices
that implement the standard to speak to each other.
A fully compliant RS-485 port is included in the Pentair Pentek
Intellidrive® Constant Pressure Pump Controller system to
permit serial connections among more than two devices on
an RS-485 compliant network. Figure 19 shows two-wire
connection to the Intellidrive.
LIGHTNING/SURGE PROTECTION
Lightning arrestors or other surge suppressing devices
can be used with this product. MOV (Metal Oxide Varistor),
SOV (Silicon Oxide Varistor).
RETROFIT APPLICATIONS
When retrofitting an installation, most of the preceding text can
be applied. As a convenience, the recommended Service Factor
Amps for non-Pentek motors is provided in Table 7.
Always verify Service Factor Amp values from current
manufacturer literature.
