Page 7: Installation
3.1.1.1 Installation checklist Verify the contents of the product shipment to confirm that you have all parts and information necessary for the installation. Make sure that all electrical safety requirements are met for the environment in which the controller will be installed. -
Page 8: Electrical Wiring
3.1.3 Electrical wiring Plug bar on the back face of the controller; connect up the controller at the rear following the wiring diagram; wire cross section max. 1.5 mm To avoid cross interference all low voltage measuring lines and pilot wires must be encased in a shielded cable (the shielding must be earthed one-sided) The control leads must be fused externally to protect the output relays. -
Page 9: Display And Operation Level
4.2 Display and operation level Setpoint value setting Briefly press the button (do not hold) A flashing frame with the description SP shows the activated setpoint level. The upper text display shows the parameter name “SP=” and the adjusted value, the lower text display optionally shows a description text. -
Page 10: Parameter Settings Level
4.4 Parameter settings level Access from the operating level Depending on the controller type, the operating level has to be unlocked with a switch on the back panel of the device. After polling (see instructions for level PARA 1 / 2), a flashing frame with the description PAR1 / PAR2 shows the activated parameter level. -

- Page 13 Selectable switching functions (depending on version): For setting please refer to configuration level under REL* Switching functions for trailing contacts: LC A Break contact on either side of setpoint (Limit comparator). Relay drops out as deviation increases (Aus = off) LC E Make contact on either side of setpoint (Limit comparator).

Page 14: Manual Optimization
4.6 Manual optimization An optimum adaptation of the control parameters (P, I, D) is necessary in order to balance an appearing deviation as quickly, non-oscillating and exactly as possible, according to the given operating conditions. Generally these adjustments require a lot of professional knowledge that cannot be replaced by this brief information. -
Page 15: Maintenance And Repair
5 Maintenance and repair 5.1 Calibration All our Viscomaster Systems are calibrated in the factory. An accuracy check and recalibration is offered at Aquametro Oil & Marine, this is usually dependent on customer, operator or regulation requirements. This interval depends largely on the operating conditions, process liquid and the application the system is installed in. -

6.2 Process troubleshooting Problem Possible causes Recommended actions Viscosity reading Normal process noise Check your process conditions. oscillating Two-phase flow Check for two-phase flow, Deposition or coating, especially stratification, or settling. Install a asphaltenes, on the tines pump. Check for environmental Contaminants in the process fluid conditions that produce stratification (e.g., a heat source). - Page 19 P = proportional band Xp (%): Lower value = longer impulses (three-point step control), more sensitive reaction, Higher value = shorter impulses (three-point step control), less sensitive reaction. Examples: Oscillating temperature/viscosity without distinct initial overshoot: P (Xp) too low Setpoint is reached very slowly after initial overshooting: P (Xp) to high I = Integral action time Tn (min): Lower value = shorter impulse gaps (three-point step control), faster balancing...
