2.1 INSTALLING THE DUAL-RELAY OPTION BOARD
To install the dual-relay option board, follow these steps (refer to the Figure 2-1):
!AUTION: The meter has no power-on switch, so it will be in operation
as soon as you apply power.
!IMPORTANT: Disconnect the power from the unit before installing this
option board.
1. Hold the board in a horizontal position, with the TB3 connector facing towards the
rear of the meter.
2. Line up the 3 connectors located on the back side of the board with pin groups J3, J4
and J5 on the mother card.
3. Push connectors down to secure on relay board.

2.2 SETTING UP THE DUAL-RELAY OPTION BOARD
You may enter a setpoint from -99999 to 999999 with a decimal point in any of the following
positions: 9.9.9.9.9.9. After applying the scale factor and offset, the displayed measurement is
compared to the setpoint alues.
LO ALARM
Displayed alue is less than Setpoint LO
HI ALARM
Displayed alue is more than Setpoint HI
HYSTERESIS
Relay 2 is energized when display alue is more than Setpoint HI. Relay 2 is not
energized when display alue is less than Setpoint LO
Setpoint Example:
Setpoint H is 500.0 and Setpoint LO is 100.0.
Reading changes from 0 to 600 and back to 0.
Figure 10-2 on the following page illustrates Table 2-1.

2.2 SETTING UP THE DUAL-RELAY BOARD ( ontinued)
Figure 2-2. Setpoint Example Illustration
To con ert Setpoint LO to a second high setpoint, set software switch 3 of the configuration
menu to 1 (ConFIG = XX1XXX). LO ALARM becomes acti e when the reading is greater (more
positi e) than that setpoint.
To con ert both setpoints to latched setpoints, set software switch 2 of the configuration menu to
1 (ConFIG =X1XXXX). When relays are energized, they stay energized until a Reset (either
front-panel or back connector reset).

2.3 ELE TRI AL ONNE TION AND SPE IFI ATION
Each relay has a form C contact. Refer to Figure 2-1 and Figure 2-3 to locate contacts and S5
switch.
* Install S5-A to control Relay 2 with hysteresis action.
* Install S5-B to control Relay 2 with setpoint HI.
* TB3-1 is a normally closed contact of relay 1.
* TB3-2 is a normally open contact of relay 1.
* TB3-3 is a common contact of relay 1.
* TB3-4 is a normally closed contact of relay 2.
* TB3-5 is a normally open contact of relay 2.
* TB3-6 is a common contact of relay 2.
