It is essential that this manual be thoroughly reviewed, with full comprehension of the matters explained herein, before attempting installation and start-up. The materials and workmanship incorporated into the Aquametro Viscosity Control System are designed to provide trouble-free service throughout the equipment lifetime. However, like any rotating equipment,...
The controllers are preconfigured and designed for a wide variety of control processes with a focus on maritime applications for viscosity control systems. A controller may be part of a complete Aquametro Viscosity Control System. For instructions covering the other components of this system, refer to the separate MBA as supplied with these components.
TFT display NOTE! Controller settings pre-configured for Aquametro Oil & Marine VCS system (Sensor – AOM Viscomaster / Valve control – AOM steam/thermal oil valve with electrical actuator). Our standard settings are optimized for the AOM VCS system. If another system is used, parameter and settings can be adjusted accordingly.

2.4 Controller Installation 2.4.1 Mechanical Installation Numerous external factors can affect the controller's successful operation. To ensure that your system works correctly, consider the factors covered in this section when designing your installation. Make sure that all electrical safety requirements are met for the environment in which the controller will be installed.
3 Controller operation Default values Default values for your controller are configured at the factory. The specific values are determined by the options that were specified on the purchase order. These are provided on the configuration sheet that was shipped with your controller. 3.1 Putting into operation Switch on power supply.
3.2 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.
3.4 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.

Configuration 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. Polling: press and hold the button, additionally press the button, hold both buttons for >5 sec, release them after the display reacts: A flashing frame with the description CONF shows the activated parameter level.

Selectable switching functions (depending on version): For setting please refer to configuration level under REL* Switching functions for trailing contacts: Break contact on either side of setpoint LC A (Limit comparator). Relay drops out as deviation increases (Aus = off) Make contact on either side of setpoint LC E (Limit comparator).
3.5 Optimization Control process (manually) 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.
3.6 Manual optimization To balance any appearing deviation as quickly a non- oscillation operation conditions of the PID Loop is required. I = Integral action time Tn (min): P = proportional band Xp (%): Lower value = shorter impulse gaps (three-point Lower value = longer impulses (three-point step control), faster balancing step control), more sensitive reaction,...
