MODEL PAXCDS -SETPOINT OUTPUT OPTION CARDS

DESCRIPTION

This bulletin serves as a guide for the installation of PAX Setpoint cards. The
setpoint cards are available as dual relay, quad relay, quad sinking transistor,
quad sourcing transistor/SSR drive, or dual triac/dual SSR drive outputs.

INSTALLING A PAXCDS OPTION CARD

Caution: The option and main circuit boards contain static
sensitive components. Before handling the cards, discharge static
charges from your body by touching a grounded bare metal
object. Ideally, handle the circuit boards at a static controlled
clean workstation. Dirt, oil or other contaminants that may
contact the circuit boards can adversely affect circuit operation.
Warning: Exposed line voltage may be present on the circuit
boards when power is applied. Remove all power to the unit AND
load circuits before accessing the unit.
1. When handling the main circuit board, hold it by the rear cover. When
handling the output card, hold it by the terminal block.
2. Remove the main assembly from the rear of the case by squeezing both finger
holds on the rear cover and pulling the assembly out of the case. Or use a
small screwdriver to depress the side latches and pull the main assembly out
of the case. Do not remove the rear cover from the main circuit board.
3. Install the output card by locating the PAXCDS output card slot location on
the main circuit board. Align the option card terminal block with slot # 3
terminal block position of the rear cover. Align the PAXCDS connector with
the main circuit board option card connector and then press to fully engage
the connectors. Verify that the tab on the option card rests in the alignment
slot on the display board.
4. If installing a PAXCDS60 option card; a knock-out on the top of the PAX case
will need to be removed to allow the PAXCDS60 top terminal block to be
inserted later. Locate the
Option, Option Slot 3, location. When looking at the case from the back with
knock-outs on top, it is the
remove the knock-out, being careful not to remove any additional knock-outs.
Trim any knock-out tabs (gates) that remain on the case. Complete Step 5 and
then plug the PAXCDS60 top terminal into the PAXCDS60.
5. Slide the assembly back into the case. Be sure the rear cover latches fully
engage in the case.
6. Apply the option card label to the bottom side of the unit. Do not cover the
vents on the top surface of the unit. The surface of the case must be clean
for the label to adhere properly. Apply the label to the area designated by the
large case label.
