Canrig Drilling Technology Ltd. 5-11
Hot Oil Warning, Setpoint, & Bypass – Indicates oil temperature has risen above the setpoint. When this
warning is displayed, the pump motor is shut off. The warning and subsequent shutoff can be bypassed for
15 minutes by pressing F5 on the HMI screen to allow the Operator to complete the current operation prior
to troubleshooting the problem. If the temperature remains above the hot oil setpoint, the pump motor will
shut off again after the 15 minutes.
High Hyd. Pressure – Indicates the hydraulic system has over-pressured (above 5200 psi), resulting in
shutdown. Call Canrig Service.
Hyd Oil Filter Blocked – Indicates the hydraulic in-tank return filter (Figure 3-15 and Figure 3-16 in
Chapter 3) is plugged and the element must be changed. Disregard this error if the oil is colder than
70ºF (21ºC). This message is also displayed if the oil is above 70ºF (21ºC) and there is less than 20 psi on
the return oil filter pressure gauge while operating the carrier. Call Canrig for Service.
Low Hyd. Oil Level In Tank – Indicates a low level in the hydraulic reservoir resulting in shutdown. Check
the entire unit for hydraulic leaks. Refill the tank to the correct level as shown by the site glass on the tank
(Figure 3-15, page 3-16). This error will not clear until the tank is properly filled with oil.
Safety Curtain Blocked – This occurs when the safety curtain is interrupted while the carrier is being lifted
or lowered. Remove the obstruction and/or clean the sensor lens, then press the RESET button on the
wireless terminal or control console. If a sensor is damaged, press F6, then press RESET to override the
error and continue operation. During rainy, foggy, snowy or dusty conditions you may need to use the
Safety Curtain Override until the sensor can be kept clean. The Safety Curtain Override On message will
display continuously until it is turned OFF. If the sensor(s) is damaged, call Canrig for service.
Safety Curtain Override On – Indicates the Safety Curtain Override function has been activated, allowing
the unit to operate without safety curtain protection. To turn the Safety Curtain protection back on, press F6
and then press the RESET button on the wireless terminal or control console.
NOTE
The Hot Oil Warning bypass will not override the
pump motor shutdown if oil temperature reaches
the Hot Oil shutdown setpoint.
Caution
Before operating with safety curtains overridden,
make sure personnel and objects are clear of
the equipment.
