1.2 SAFETY ONSIDERATIONS

Refer to your main owners guide manual for complete safety considerations.

This option card is intended for use in a DPF700 panel mount de ice that is protected in

accordance with Class I of EN 61010 (115/230 AC power connections). Installation of this

instrument should be done by Qualified personnel.

• Do not exceed oltage rating on the label located on the top of the instrument housing.

• Always disconnect power before changing signal and power connections.

• Do not use this instrument on a work bench without its case for safety reasons.

• Do not operate this instrument in flammable or explosi e atmospheres.

• Do not expose this instrument to rain or moisture.

• Unit mounting should allow for adequate entilation to ensure instrument does not

exceed operating temperature rating.

• Use electrical wires with adequate size to handle mechanical strain and power

requirements. Install without exposing bare wire outside the connector to minimize

electrical shock hazards.

Note ☞

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.
