C-mac® Monitoring of all static 3-phase parameters: Over / Undervoltage, Sequence, Asymmetry, Frequency. Monitoring of dynamic parameters: df/dt (ROCOF) and Phase angle fault. Programmable functions, ranges and reaction delays. 2 independent relay output 8 A / 250 V AC AC supply voltages up to 3 x 415 VAC Made in accordance with the C€ and EMC regulations Over voltage: Under voltage: Asymmetry: Neutral detect: Frequency: Frequency limits: df/dt (ROCOF): Phase shift: Delay, release: Delay, activate: Delay, start-up: The C-mac® module type PPR10 is a universal 3-phase monitoring relay, particularly suitable for monitoring and protection of the mains supply and connected equipment in connection with generators and portable equipment. The unit is made in accordance with the new European requirements for connection of micro-generators to the mains supply. All parameters are programmable, and in order to ensure that unauthorized persons are not able to change the settings, there are no potentiometers on the unit. The parameters are selected on a PC, and transferred to a small battery operated programming unit, which is then used to program each unit on site. The unit is supplied with two relay outputs, and you can program which of the parameters are active on each relay. The relays are activated at normal conditions, and releases if one or more of the selected parameters are exceeded. Reaction delays for each relay are individually selectable, except for the dynamic parameters, where the reaction delay for release is fixed at 100 msec. Each output relay have a corresponding control input, where you can select between 5 different functions. During start-up delay, the relay remains activated, also if one of the selected parameters detects a fault. This is to ensure, that the units does not release f.inst. when the generator is connected to the mains. Functions, control input: None: Control input not used, relay indicate parameter conditions. Enable: Relay only active, if input is activated and parameter conditions are OK. Latch: Relay activates, when the input activates and parameter conditions are OK. During operation, the input must remain activated. If the relay has released after a fault detection, the input must be released and activated again, before the relay can activate. Reset: Relay activates, when the input activates and parameter conditions are OK. After this, the input can be released. If the relay has released after a fault detection, the input must be activated again, before the relay can activate. Auto: Relay activates, if the parameter conditions are OK. When the input is activated, the start-up delay starts, and after this delay, the unit operates as in the function "none". A new start-up delay is activated, if the control input releases and activates again. Programming: In order to program the unit, you must have a programming unit, INTF3. Together with the programming unit, you get a corresponding software, which you must install on a PC. You can also download the software from our website: www.comadan.com. When the program is activated you select all the parameters, which is then transferred to INTF3 via a cable connected to one of the COM-ports. After this, you disconnect INFT3 from the PC, and you can now transfer the program to the PPR10 via the infrared transmitter in front of INTF3, if the PPR10 is connected to the mains supply. If the transmission is completed in the correct way, the top LED "control 1" and after this the LED "supply" will flash once. If the transmission is not OK, the LED's will flash several times.
