2 INSTALLATION

2-19

A twisted pair of wires should be used for connection
to an external switch. Connection to the 269 is made
via a terminal block which can accommodate up to
#16 AWG multi-strand wire.

2.16 Display Adjustment

Once the 269 relay has been installed and input
power applied, the contrast of the LCD display may
have to be adjusted. This adjustment has been made
at the factory for average lighting conditions and a
standard viewing angle but can be changed to
optimize the display readability in different
environments. To alter the display contrast the
trimpot on the rear of the unit marked "CONTRAST"
must be adjusted with a small slotted screwdriver.

2.17 Front Panel Faceplate

The front panel faceplate is composed of a
polycarbonate material that can be cleaned with
isopropyl or denatured alcohol, freon, naphtha, or
mild soap and water.

2.18 269 Drawout Relay

The model 269 relay is available in a drawout case
option. The operation of the relay is the same as
described elsewhere in this manual except for the
differences noted in this section. The physical
dimensions of the drawout relay are as shown in
Figure 2.11. The relay should be mounted as shown
in Figure 2.12.

The drawout 269 relay can be removed from service
without causing motor shut-down. This can be useful
for replacing, calibrating, or testing units.

RELAY MOUNTING - Make cutout as shown and drill
six 7/32" holes on mounting panel. Approximately 2-
1/2" should be clear at the top and bottom of the
cutout in the panel for the hinged door. Ensure that
the five #6-32 nuts are removed from the threaded
studs in the mounting flange and that the drawout
chassis has been removed from the drawout case.
Install the case from the rear of the mounting panel
by aligning the five #6-32 threaded case studs to the
previously drilled holes. With the studs protruding
through the holes secure the case on the right hand
side with two #6-32 nuts provided. Install the hinged
door on the front of the mounting panel using three
#6-32 nuts provided.

FIELD ADJUSTMENTS - There are four screws
holding the plastic 269 case to the drawout cradle.
These screw into holes which are slotted to
compensate for panel thickness. If the 269 case is
mounted at the extreme end of the slot intended for

thin panels, the relay will not seat properly and the
door will not shut over the relay when installed on a
thick panel. Loosening the screws and moving the
relay forward before retightening will fix the problem.

RELAY REMOVAL - Open the hinged door. Next
remove the two ten finger connecting plugs making
sure the top one is removed first. Swivel the cradle-
to-case hinged levers at each end of the 269 cradle
assembly and slide the assembly out of the case.

RELAY INSTALLATION - Slide the 269 cradle
assembly completely into the case. Swivel the hinged
levers in to lock the 269 cradle assembly into the
drawout case. Install the two ten finger connecting
plugs making sure the bottom plug is installed first.
Close the hinged door and secure with the captive
screw.

NOTE: There must be at least ½" clearance on the
hinged side of the drawout relay to allow the door
to open.

IMPORTANT NOTE: When removing the drawout
relay cradle assembly the top ten finger connecting
plug must be withdrawn first. This isolates the 269
output relay contacts before power is removed from
the relay. When installing the drawout relay cradle
assembly the bottom ten finger connecting plug must
be installed first. This causes power to be applied to
the 269 relay before the output relay contacts are
placed in the circuit.

After a 269 relay cradle assembly has been removed
from the drawout case it is recommended that the
hinged door be closed in order to reduce the risk of
electric shock.

Due to the hardware configuration of the drawout
relay shorting bars, the RELAY FAILSAFE CODE
(SETPOINTS, page 5) should not be changed without
consulting the factory. Spare shorting bars are
included with each drawout specifically for the
required modification. Wiring for the 269 drawout is
shown in Figure 2.13. If it is required that any of the
output relay configurations in Figure 2.13 be different
than shown, this information must be stated when the
relay is ordered.

The 269 Drawout does not meet the IEC947-1 and
IEC1010-1.

No special ventilation requirements need to be
observed during the installation of this unit
