Rockwell Automation 810 5.0: Inverse Time Current Relays - Manual (Page 3)

ADDING DASHPOT FLUID - (See note
Page 2 ) The dashpot fluid is shipped
separately. To add fluid, remove the core
and dashpot
assembly by unfastening
the spring clamp. Remove the dashpot
cover by pulling the core straight out of
the dashpot Remove and discard red
plastic shipping spacer if present. Add
the silicone fluid with the dashpot cover
removed, with the piston and core in
place. Fill the dashpot to the top of the
three round projections on the piston.
See illustration below. The fluid must be
free of dirt or grit, and the dashpot and
piston must be absolutely clean.
Check fluid level periodically,
COIL CURRENT - The maximum continuous current rating of the coil appears on the
relay nameplate. The current at which the relay is set to trip should not exceed this
value except when an additional device protects the coil against sustained overcur-
rent. To avoid relay damage, current through the relay coil must be interrupted after
the relay trips. Relay can carry rated continuous current in the non-tripped position
only.
OPERATING TIME ADJUSTMENT - Un-
less ordered with a specified time delay
setting, the relays are set for minimum
time delay when shipped. To increase
the time delay, remove the piston from
the dashpot and decrease the opening
of the adjustment valve by rotating its
cover counterclockwise. See illustration
below.

The range of operating times possible
with the Bulletin 810 is shown by the
time-current characteristics curves on
Page 2 . Note that the curves cover all
possible combinations of two different
dashpot constructions and four different
fluids. Series A dashpot components
and Series A red and blue fluids are no
longer available, but can continue to be
used as indicated. Series B blue fluid is
supplied as standard. Higher viscosity
“clear” fluid will be supplied when
requested.

Catalog numbers are for single relavs in the ooen tvoe construction. with NC contacts and an automatic
reset. The calibration table also applies to catalog numbers beginning with the letter B, C, K, or L, and
ending with letter B. C. or D.

Each area is bounded by curves that
represent the operating times with the
valve fully opened and fully closed. In-
termediate settings must be verified by
electrical tests.
