ROTEM warns and alerts all users that the Product is inherently complex and may not be
completely free of errors. ROTEM's products are designed and manufactured to provide
reliable operation. Strict tests and quality control procedures are applied to every product.
However, the possibility that something may fail beyond our control exists. Since these
products are designed to operate climate control and other systems in confined livestock
environments, where failure may cause severe damage, the user should provide adequate
backup and alarm systems. These are to operate critical systems even in case of a ROTEM
system failure. Neglecting to provide such a backup will be regarded as the user’s willingness
to accept the risk of loss, injury and financial damage.
In no event will ROTEM be liable to a user or any third party for any direct, indirect, special,
consequential or incidental damages, including but not limited to any damage or injury to
business earnings, lost profits or goodwill, personal injury, costs of delay, any failure of

2 PRECAUTIONS
•Grounding
•Checking the Battery Level
•Frequency Inverters
2.1 Grounding
•Always connect temperature and sensor shields to earth ground. Avoid mixing high voltage
wiring with sensor and low voltage wiring.
•Keep the controller as far as possible from heavy contactor boxes and other sources of
electrical interference.
•Do not connect communication wire shields, which go from one house to another at both
ends. Connect them at one end only. Connection at both ends can cause ground loop
currents to flow, which reduce reliability.
•The COM connection for communications is not the shield wire. The COM, RX and TX wires
must connect to each other at all controllers.
2.2 Checking the Battery Level
Check the battery once a year. The output must be 2.7 volts (minimum). Authorized personnel only
must replace the battery if the output is below the minimum required level or every five years.
2.3 Frequency Inverters
Frequency inverters can cause severe electrical and electromagnetic interference. Therefore, when
employing a frequency inverter, it is critical that you carefully follow the manufacturer's installation
instructions.
In particular verify:
•that the cable shielding between the inverter and any motor meets industry standards
•proper grounding of the inverter's chassis and motor power cable
•proper grounding of low voltage cable shield wire
•that the controller and inverter cables are kept in separate conduits or wire bundles

3.2.1 SuperGuard
SuperGuard provides you maximum capability with minimal complexity in programming and controlling
up to 10 Piguard Plus units.
SuperGuard is the ultimate pig house controller. Equipped with an easy programming interface, it
provides programmable outputs for all major features and a 4 x 20 character LCD that provides display
feedback on the programming and device status.
The SuperGuard communicates with up to ten Piguard Plus units to access history, collect events and
alarms for each and all relevant data up to 100 days.
3.2.2 Piguard
Piguard Plus is ROTEM’s latest advance in environmental controllers specially designed for the pig
house industry.
The user-friendly has high performance and quick response time. Piguard Plus features accurate
temperature and humidity sensors, secure transmission of data even in noisy environments and the
added convenience of eight output relays as well as four analog outputs.
Each Piguard Plus can operate independently in case of SuperGuard malfunction or loss of power.
Using an internal battery when the Piguard Plus is operating “alone”, there is no history collection or
possibility to change parameters.
There are three Piguard Plus models:
•Piguard 80: No variable speed
•Piguard 81: 1 channel variable speed
•Piguard 82: 2 channels variable speed

PIGUARD provides separate temperature curves for growth day, target temperature, heat temperature,
tunnel temperature and low/high alarm temperatures. The controller creates a curve for each one and
uses it as a reference. The program alters at midnight prior to the next day on the next row
programmed. There are up to 10 programmable rows, but the controller maintains yesterday’s settings
for every empty line; therefore it is not necessary to fill the entire table.
Limits:
•Day: 0 - 999
•Target: 0 - 40° C
•Alarm low: 0 - 40° C (without floating point)
•Alarm high: 0 - 40° C (without floating point)
5.2 Min. Max. Level
The Minimum/Maximum Level menu sets the current absolute minimum and maximum ventilation levels
available. There are five minimum/maximum level choices:
•Min/Max by Growth Day
•Soft Min/Max by Day
•Min/Max by Time of Day
•Soft Min/Max by Time
•Cold/Warm (refer to Setting Cold Warm Levels, page 22)
•By Weight (refer to By Weight, page 23)
