Primus V Controller System Overview
The Primus V Controller is a product which complements the Optio V gas monitor. The Primus V has the
ability to gather and display real time data from Optio V units. This controller has optional 24Vac/24Vdc
input power with a maximum power consumption of 2.5A at maximum load. There are six onboard
relays that are freely programmable using Subcon logic. The Primus V has a user-friendly four button
keypad used for menu navigation and a graphical LCD that displays detailed monitor information. Two
local 4-20mA outputs, 12 remote modbus 4-20mA outputs, 1 local Strobe and Horn output port and
three RS485 Modbus RTU Scan Ports that support a total of 96 multi-gas monitors. Each gas monitor has
the ability to support six gas sensors enabling users to build a comprehensive gas detection network.
CAUTION
THE UL61010-1 CERTIFICATION OF THE PRIMUS V CONTROLLER LIMITS ALL ELECTRICAL CONNECTIONS
INSIDE THE UNIT TO A MAXIMUM OF 60VDC/30VAC. ELECTRICAL CONNECTIONS EXCEEDING THESE
WILL OPERATE THE UNIT OUTSIDE OF THE CONDITIONS OF ITS CERTIFICATION.

Purpose:
The Primus V Controller is a product to be used in an ordinary location to remotely monitor and manage
connected multi-gas monitors. It is intended to connect to the Optio V monitor and can also be
connected to a centralized control and automation systems. The Primus V is intended to be
programmed using Subcon software, allowing users to design and create complex and custom networks.
Users can configure the six onboard relays and local strobe and horn using built in logic on the Subcon
software. It also gives the user the ability to configure the two local 4-20mA outputs as well up to twelve
remote modbus 4-20mA outputs that can be utilized for fan control. All Primus V controllers will come
with a preconfigured mode of operation.

UNCOMFORTABLE WITH INSTALLATION, CONTACT A LICENSED ELECTRICIAN.
FOLLOW YOUR LOCAL LOCKOUT TAGOUT PROCEDURE BEFORE MAINTAINING ANY REMOTE
CONTROLLED EQUIPMENT. ALWAYS REMOVE ALL ELECTRICAL POWER FROM ELECTRICAL EQUIPMENT
BEFORE ATTEMPTING ANY INSTALLATION PROCEDURES. DEENERGIZE AND TAGOUT ALL SOURCES OF
ELECTRICAL POWER BEFORE TOUCH-TESTING ANY EQUIPMENT. FAILURE TO FOLLOW THIS WARNING
COULD RESULT IN SERIOUS INJURY OR DEATH AND DAMAGE TO EQUIPMENT.
THE UNIT MUST BE WIRED TO THE CORRECT VOLTAGE AS REQUIRED BY THE ACTUAL LINE VOLTAGE
AND SIGNALS MUST BE CONNECTED TO THE CORRECT TERMINALS. FAILURE TO FOLLOW THIS
WARNING COULD RESULT IN SERIOUS INJURY OR DEATH AND DAMAGE TO EQUIPMENT.
Mounting Location: To ensure Primus V functionality is consistent the following instructions shall be
followed. Select a location to mount the monitor to best suit the needs of the room or facility. Avoid wet
locations and locations where physical damage is possible to unit.
Mounting Instructions: The Primus V enclosure comes fully built with 4 mounting feet, for quick and easy
installation. Mounting directly to the wall or uni-strut are common practices. Use steel or stainless steel
5/16”bolts, minimum length of 1” to ensure the panel is securely mounted to the desired medium.

The green dotted area in the block diagram below is the designated area where the user is allowed to drill
holes for the purpose of making connections to any of the internal available ports on the PVC board.
Appropriately sized cable glands are to be used to reduce opening size. Any unused holes must be properly
closed off with blanking plugs of the appropriate size.

Wiring Instructions:
1. Read this manual before installation.
2. Please observe appropriate local and National Electrical Codes when wiring electrical devices.
3. Do not connect or disconnect wiring or perform circuit checks while the power is turned on.
4. The relay wiring, Modbus RTU RS485 wiring, 4-20mA wiring, Strobe and Horn wiring and the power
wiring should be in separate metal conduits. All wiring coming to or from PVC unit must have
flammability rating of at least VW-1. (including customer provided wiring)
5. Low voltage wires shall be wired with proper low voltage class wiring procedures.
6. All terminals shall be tightened to specific terminal torque 4.4 IN-LBS(0.5N·m), unless otherwise
specified
7. Remove excess metal screws, metal filings, and wire clippings from inside of unit
8. Inspect to make sure no exposed wire has contact with any other wiring terminals
9. RC type suppressors are strongly recommended on all contactors
10. The power supply to the Primus V must have a master disconnect and should be fused.
Input power wiring options: Max 24Vac/Vdc
WARNING
FOR 24V CONNECTIONS: A UL REGISTERED CLASS 2 TRANSFORMER OR POWER SUPPLY MUST BE

The Primus V controller is cable of handling multiple different Input and output types. Below is a field wiring for each
option:
Relay Descriptions
Control Relay (Failsafe Operation)
When the gas concentration value reaches the user set point and the user configured program logic in
Subcon is met, the relay coil selected will de-energize. This may be used to turn on a exhaust fan for the
purpose of clearing an enclosed space. As an added safety feature after the gas value has dropped below
the desired set point this relay will remain de-energized (fan remains on) for a user configured period of five
minutes. This is to ensure complete removal of hazardous gases and prevents the relays from short cycling.
Alarm Relay (Normal Operation)
When the gas concentration value reaches the user set point and the user subcon program logic is met the
relay coil selected will energize. It is used to activate audible and/or visual indicators at remote locations.
Trouble Relay (Failsafe Operation)
Relay coil will de-energize if the Primus V losses communication with the sensor/monitor or recognizes that
it has drifted either above or below its capabilities.
