SECTION 1: INTRODUCTION
1.1 PURPOSE OF THIS GUIDE
The purpose of this guide is to provide installation and commissioning procedures and basic installation and operating instructions for the ONICON System-10-N2 serial interface.
1.2 TYPICAL SYSTEM-10 NETWORK INTERFACE MODULE
ONICON’s System-10 is a true heat (Btu) computer which accepts data from several sensors, performs a series of computations with that data, and displays and/or transmits the results as an indication of the amount of heat (Btu’s) being transferred per unit time or as a totalized amount. It can also be provided with an optional Metasys building control network.

1.4.2 Optional Network Interface With Isolated Digital Pulse Input (Di3)
The System-10 BTU Meter can be provided with an auxiliary pulse input for totalizing pulse outputs from external devices such as water or gas meters. Pulses are accumulated in an internal register, and the totalized value is available on the network. This register can be zeroed via the network. The maximum register total is 9,999,999. The register will rollover to zero when this value is exceeded.
If the auxiliary pulse input option was ordered at the same time the Btu meter was ordered, it will arrive fully congured and ready to use. If it was ordered after the Btu meter was delivered and is being installed as a eld upgrade, it may be necessary to congure the pulse input. The information required to congure the input is provided below and on the following pages:
The input pulse must meet the following criteria:
1. Frequency input range, 50 Hz maximum
2. 10 millisecond minimum pulse duration
Input Pulse Denition:
In order to congure the communications card auxiliary pulse input, you must rst determine which type of pulse your meter produces. The allowable types of input pulses are described on the following pages. Based on the type of pulse, set the selector switch (S1) on the communications circuit board (Fig. 1) to the correct setting.

Powered Pulse:
This type of output refers to a pulse which has an associated voltage with it (see Fig. 2). Set the selector switch, S1 to Pwrd Pulse. The allowable voltage range is 5-24 VDC. The input impedance is set at the factory to be 11 KOHM via the impedance selector jumper (J1, see Fig. 1). A lower impedance, 3 KOHM can be selected if required by the instrument providing the pulse output. Consult the instrument manufacturer or ONICON if you are uncertain as to the proper jumper selection.

Open Collector (Sourcing):
This type of output refers to an open Collector Switch congured for a sourcing function (see Fig. 3). Set the selector switch, S1 to SRC. The switch must be rated for at least 20mA at 20VDC.

Open Collector Sinking or Dry Contact:
This type of output refers to an open collector switch congured in a current sinking arrangement or a dry contact switch (see Fig. 4 and 5). Set the selector switch, S1 to Sink. In either case, the switch must be rated for at least 20mA at 20 VDC.

1.5 RS485 BIASING AND TERMINATION
The ONICON System-10-N2 does not provide biasing voltage or termination to the RS485 network. A 120W termination resistor should be used when the meter is installed at the end of the line.
1.6 NETWORK ADDRESSING
Before the System-10 can communicate on the N2 network, the appropriate device address must be programmed into the meter. The N2 network address for ONICON System-10 BTU Meters may be set to any address from 001 to 255. This address is set at the Btu meter. Section 1.6.1 details the procedure for changing this address.
1.6.1 Changing the Device Address
Every ONICON System-10 is individually programmed at the factory with application specic data provided by the customer during the ordering process, and this may include network addressing information. If the device address information was provided, the meter will be programmed with that number. If no address is provided, ONICON Btu meters are programmed with a default address of 017. The address may be changed at the System-10 using the procedure outlined in the table below.

SECTION 3: NETWORK TROUBLESHOOTING TIPS
3.1 TROUBLESHOOTING
Reported Problem Possible Solutions
Device will not communicate with the network controller.
• A unique address is required for each device on the network. Duplicate addresses will cause some or all of the devices on the network to quit working. (See section 1.6.1 of this manual for details.)
• The RS485 network cable connections are polarity sensitive and must be connected the same way on every device. (i.e. + to + and
- to -). (See section 1.4.1 of this manual for details.)
• Shield drain connections should be daisy chained in the same manner as the signal cables for RS485. The shield drain wire should be left unterminated at the end of the cable and connected to earth only at the supervisory controller. Shield wires must not be connected to the RS485 connector on the System-10.
• The maximum number of devices allowed on a RS485 network segment without a repeater is 32. Adding more than 32 devices to a single segment may reduce the transceiver output voltage to a level that is too low to be distinguished from background noise on the cable.
• RS485 cable impedance should be matched to a termination resistor at the end of the cable. ONICON boards do not have a resistor for termination. A resistor should only be used if the display is the last device on the network cable. (See section 1.5.1 of this manual for details.)

Reported Problem Possible Solutions
Network communications are disrupted when the device is connected.
• The RS485 network cable connections are polarity sensitive and must be connected the same way on every device. (i.e. + to + and - to -). (See section 1.4.1 of this manual for details.)
• A unique address is required for each device on the network. Duplicate addresses will cause some or all of the devices on the network to quit working. (See section 1.6.1 of this manual for details.)
• Shield drain connections should be daisy chained in the same manner as the signal cables for RS485. The shield drain wire should be left unterminated at the end of the cable and connected to earth only at the network master controller. Shield wires must not be connected to the RS485 connector on the System-10.
