I INITIAL STEPS
1. Turn off power to the instrument.
2. Examine the parts furnished in the kit to plan where each part will be fitted, using Figures 1, 2 and 3 and item
no.’s, e.g. (#1).
ll INSTALLING OPTIONS BASEPLATE
1. Open the door to the recorder to show the platen. On the right hand side of the platen there is a single slotted
countersunk screw. Loosen this captive screw by turning it counterclockwise. Lift up the platen and secure
open with a suitable retention device.
2. Locate the power supply module situated in the bottom right hand corner of the case. Obtain the Options
baseplate (#8) and four 43 mm hexagonal spacers (#7) from the kit. Locate the four screw locations
identified as (#9) on the top part of Figure 1. Using the options baseplate and figure 1, locate the positions
for inserting the four 43 mm hexagonal spacers. Screw the spacers in position and tighten carefully with a
socket wrench.
3. Obtain four screws (#2) and washers (#1) from the kit. Position the Options Baseplate on top of the four
hexagonal spaces with the flanges pointing towards the back of the case. Secure the Options Baseplate
to the hexagonal spacers using the four screws (#2) and washers (#1). Carefully tighten with a socket wrench.
IlI INSTALLING OPTION BOARDS
There is no required order for options boards. Their order should be decided by the ease of wiring to them.
A relay board with several sets of wires will probably be best as board #1. Wire board #1 connections before
any other boards are mounted. Be careful to keep ac power wires away from low level dc connections to the
channel inputs.
If installing only option board 2 and/or 3 go to the second part of step 3 (*) and skip steps 4 & 5.
1 . Open the lower power supply connector (see connector detail), and insert one end of the long (24 mm)
ribbon and press the connector closed.
2. Thread the long ribbon through the slot in the power supply mounting plate, and fold at right angles upward
(see diagram dotted lines). Fold so that the ribbon side with the silver connection edges is AGAINST THE
PLATE. The left side of folded ribbon should be approx. ¾ inch from left edge of the plate. Place the
insulation sheet (#6) OVER the ribbon with the four holes toward the BOTTOM of the insulation sheet.
3. Mount the
first board
with two screws (#2) & washers (#1) in the bottom threaded inserts on the plate over
the recorder power supply, using the bottom hole on each side of the board. (
*
) If there is to be a
second
board
, finish the
first board
with two short (15mm) spacers (#3) in the second set of threaded inserts. If
there is no
second
board
use two more screws (#2) & washers (#1) to finish the
first board
.
4. Loop the long ribbon down to the
first board
and insert into the
top
connector. If there is to be a
second
board
, insert one end of a short ribbon into the second connection on the
first board
(just below the top
connector with the long ribbon), see diagram detail.
5. Wire to the
first board
connections. If there is no
second board
, go to step 13.
6. If there is to be a
second board
, mount two medium (21mm) spacers (#4) into the third set of threaded
inserts. Then mount the
second board
using the bottom two holes and two screws (#2) & washers (#1) into
the short (15mm) spacers (#3) (from step 3). Loop the short ribbon from the
first board
down to the
second
board
and insert into the TOP connector.
7. If there is to be no
third board
, finish the mounting with two more screws (#2) & washers (#1) and wire to the
second board
connections, then go to step 13.
8. If there is to be a
third board
, finish the second board with two short spacers (#3) into the
second board
medium (21mm) spacers (#4) (from step 6) and insert one end of a short ribbon into the connector just below
INSTRUCTIONS FOR MULTIPOINT CIRCULAR CHART RECORDER FEATURE ADDITIONS
HA250385U010 Page 2 Issue 3 Jun 99
the connection with the short ribbon from the
second board
.
9. Wire to board #2 connections. If there is no
third board
, go to step 13.
10. If there is to be a
third board
, mount two long (38mm) spacers (#5) into the fourth set of threaded inserts.
Then mount the
third board
using the bottom holes and two screws (#2) & washers (#1) into the
second
board
short (15mm) spacers (#3) (from step 8). Finish the
third board
with two screws (#2) & washers (#1)
into the long (38mm) spacers (#5).
11. Loop the short ribbon from the
second board
down to the
third board
and insert into the
top
connector and
wire to the
third board
.
12. After installing all the options required, locate two medium (21mm) spacers (#10) and install as shown on
Figure 1. Locate the RED insulator and affix in position on top of the # 10 spacers with two screws (#2) and
washers (#1).
13. Re-power the recorder and if there is a message “press ENTER to use new options”, press ENTER and allow
the recorder to complete initialization.
REMINDER
- Relays have to be configured to respond to Jobs (usually alarm Jobs) and retransmitted
outputs have to be configured to have internal values as their sources. Consult the operator and/or options
manual for configuration of new features
IV INSTALLING TRANSMITTER POWER SUPPLIES
1. Follow the INITIAL STEPS from Section
I
.
2. One or two Transmitter Power Supplies can be installed as shown in Figure 2.
3. Place the insulation sheet (#14) over the back plate posts for the board to be mounted.
4. Place a spacer (#15) on each of the four posts.
5. Using the four screws (#12) and internal tooth washers (#13), mount the transmitter power supply board on
the posts with the power transformer on the
right end
.
6. If there are
no
option boards present, go to Step 8. If there are option boards present, the option board
mounting plate must be moved to the side to reach the recorder power supply terminal board for connection
of the blue and brown power leads from the transmitter power supply boards.
7. To move the option boards and plate aside, loosen the four Plate Mounting Screws identified in Figure 1
and move the plate to the left. The bottom two plate mounting screws can be accessed
through holes in
the first option board.
If three option boards are present, the upper right screw is also accessed through a
hole in that board.
When moving the plate aside be careful not to disconnect or damage the ribbon
cable to the recorder power supply.
8. The blue and brown power leads from the transmitter power supplies go on the lower two terminals of the
recorder power supply terminal board. The blue wire goes on the bottom terminal (which already has a blue
wire attached), and the brown wire goes on the center terminal (with the already attached brown wire).
Loosen these two screws with an offset Phillips screwdriver, insert the spade lugs
from the back side
and
tighten the terminal screws.
If the recorder power supply must be dismounted in order to reach it’s terminal board screws, be
very
careful
with the ribbon cables to the option board assembly and to the microprocessor main board.
9. If the option plate was moved aside in Step 7, re-install it now.
10. Install the Shunt Resistor Assembly on the desired input channel terminal board and connect to one of the
transmitter power supply 2-pin connections - see Figure 3.

HA250385U010 Page 3 Issue 3 Jun 99
11. A 2-wire transmitter connected as shown in Figure 3 will now receive 24Vdc power from the recorder. If it is
ever required to connect a self-powered transmitter, disconnect the 2-pin connection from the transmitter
power supply board. The shunt board will then function as a simple 250 Ohm shunt resistor.
